I hope you're aware that metric time isn't dd/mm/yyyy nor ISO8601 or similar.
In the original metric system, 250 or so years ago, a week was ten days. And every day was divided into decidays and centidays.
This (luckily?) didn't catch on.
But in 1954 when they created the SI-system they settled for the second as a base for time.
So metric time is measured in decasecond, hectosecond, kilosecond or megasecond or gigasecond.
I prefer ISO8601!

Canada is metric. That's why all temperatures are in F, weights in lb and heights in feet and inches.

Why don't we just go back to the old units of measurement? We still measure horses in hands. Drinks are measured out in fingers. We should bring back the ell, the cubit, the palm and the digits. Add to that the carucate, the hide, the oxgang, the virgate, the yardland, and the quinaria.
Do people still use the barleycorn for measuring shoe sizes?
How about the lachter or the button?
Don't forget the line, the page, the rod, the step, and the stadion.
I think weights are still sometimes measured in bags, are they not? The Dutch cask is used for measuring butter and cheese, I think. How about the duella, the keel, the lot, the mark, the pennyweight, the roll, the room, the sarpler, the slug, the tod, the truss, and the whey.
I could go on and on (and on and on and on) but I think I've put just about everyone asleep by now.
The point is, if you are going to be sending code or data where it may need to be read by other cultures, either choose an international standard, or just document what standard you are using and let the user use their brain (or a calculator) from there. standards of time and measurement come and go. Some stay longer than others. All have their advantages and disadvantages. It all depends on the context of its use, and the primary audience.

That would be really nice, but over the years I've found that the bigger problem is systems using different units within the same environment, even though all are metric. E. g. in construction industry, measurements are typically given in mm, except for some that are, by some unwritten law, always presented in cm, and a few in meters (meters above sea level to be concise).
Woe to the CAD software programmer who needs to process data based on such measurements without concise information where they're coming from!  But I guess it's even worse for programmers in the U.S. ...

As long as they will be things like national pride, country specific formats, as dumb as they may be, will not disappear.
It will probably take decades to get rid of mm/dd/yyyy (which, while I understand the write-it-as-you-speak-it, has overall more disadvantages than advantages)
It will take centuries to settle for imperial or metric ( I prefer metric because more straight forward to me, but I don't care as long as we settle for something)
Flying cars is probably the only way of getting everybody to use the same side of the road for driving, and I am not even convinced about that. Maybe this will not be an issue anymore with autonomous driving.( You would not imagine what a waste of resources and time developing a left hand drive and right hand drive version of a car is).
This, as well as many other things, would have been solved a long time ago if people had common sense. But ...

The car needs to be able to do both; and it should know where to switch. There's people coming from England using the canal; if their cars only can drive left, you'd get very dangerous holidays and visits.

What about the 4th of July? Were Americans saying dd/mm/yyyy before but switched at some point, but "the 4th of July" stayed as is?
Also it doesn't really make sense to me to start with month, then day, then year. Either go from less specific to more or the other way around, but don't mix them up.
What time is it? It's 7 minutes, 35 seconds, 4 hours.

Same here. Unfortunately Duhsigners, ProderpOwners, and PointygramManagers live in a reality distortion field where everyone uses the same date format they do. At least those nitwits have no control over the backend, so it's DateTimeOffsets everywhere until the presentation code at least.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

US method mirrors how it is said when spoken.
We don't say "the sixth or April"; we say "April sixth" - and ergo, that is how we write it. How do you normally say that in Canada (for those parts that have both day and night). Even done numerically, only, we follow the spoken word. (both version put the year in the rear). In other languages they do say things like 'ersten Mai" - that's their problem and their way - I didn't bitch to them about changing the arse-backwards word order. That's their problem.
Now, for the "Euro" version - it sorts like shyte . . . worse than the US version sorts, and that a turd and a half. The year should go first, then the month, then the day - a four-digit year, at that, lest, for example, something just over a century old be classified as very current.
So that's that. I was going to use all-caps so the forgoing instructive blurb is taken and accepted as order that must be obeyed, but, feeling generous this morning I'll let you spend a bit more time adapting to before, well, THE SHIFT-LOCK.

I hear that argument a lot ("we say it like...", and I hear "4th of July" a lot, too. If you say "July 4th" or "4th of July" then both are unambiguous. The point is that if you said "7/4" or "4/7" there's ambiguity for the rest of the world.
My point is: avoiding ambiguity is pitifully easy in this case.

"Fourth of July" is a bad example. We don't normally swap in a holiday name in place of the date. Using your date, however, the date, when fully enunciated, is "July Fourth Seventeen Seventy Six" and the reverse is rarely if used at all.
The ambiguity however is in date formatting for non-technical usage (else, YYYYMMDD). That being said, the ambiguity would really exist in a local wherein the common idiom is in one order and the written version reverses that order. Jumping on the bandwagon to accommodate languages that use a reverse word order - why ? There is no ambiguity here - except for the (in our point of view) those who do it backwards elsewhere.
I haven't spent enough time in Canada to know the common speech version. Perhaps this written format is a manifestation of yet another concession to Quebec ?
What could be less ambiguous than to write something the same way it is said?

I draw your attention to the fact that the Monroe Doctrine appears to have lapsed.
As long as nations in the "New World" and the "Old World" trade, there will be a need for agreed weights and measures and agreed methods of representing them. In most modern languages*, units are typically written in decreasing order of size (5 dollars and 21 cents = $5.21; 4 pounds, 3 shillings, and 9 pence = £4 3s 9d; 5 yards, 2 feet, and 4 inches = 5yd 2' 4"), the only exception being time. This alone makes the non-ISO 8601 formats suspect.

First problem to address: French - cannot count to seventy in any rational manner. Arabic looks good at that point. Besides, aren't we taught arithmetic operations least-to-most significant digits?
The unit argument you use would be good except for one thing: Dates are Labels ! For most common usage, I haven't heard about anyone in any date format using fractional months (for example). I mean, really, months vary in length and the full day labels include one of seven flavors. For that matter, the date is different in different parts of the globe (Greenwich is not the center of the universe). Noon happens when the sun's high.
But perhaps your current date is April 63/4, 2021 or 6.75 April 2021 ?

Seriously, either arrangement - little-endian ([day fraction], day, month, year) or big-endian (year, month, day, [day fraction]) would be OK. What I object to is the "mixed-endian" representation used in the US. It is inconsistent with the way we (including the USians) represent all other measurements.
[day fraction] stands for any method of representing a day fraction, whether a [decimal fraction], [hour, minute, second], or [second, minute, hour].
