I'm thinking that one way to get something useful along these lines in iOS would be a Shortcut that clears the tracking parameters and puts the result on the clipboard. I think that's possible, and then it's a matter of using the share sheet to get the URL into the Shortcut.

Certainly has a bit more friction than this, but doesn't seem so bad if it could work. This (unfortunately ad-filled) page has an example:

I built a similar Mac app that removes common trackers from clipboard links. It works on your iPhone with Apple's Universal Clipboard.

There are apps[0] that do this via the share sheet. Share is basically the same effort as Copy on iOS so that seems pretty good.

In some cases, like AMP pages, simply using the share button in safari to copy it will get you the canonical URL, but I don‘t think that works everywhere.

If you actually use a keyboard with iOS, you could find a shortcut that does this and assign it a global keyboard shortcut via Full Keyboard Access settings.

Chrome Android copies canonical URL from the share menu. On desktop browser, I use a browser extension (CanonicalCopy) that makes available canonical link. It usually works fine on most websites. A lot of websites don't have canonical meta tag. Others have it misconfigured.

Now that Apple allows Safari extensions (with iOS 15), I wonder if it would be possible to create the functionality.

But honestly most times I copy a link, I’m going to open it in Firefox Focus. Maybe they or Brave could add the feature?

Same here. Editing the links on iOS is bloody difficult.
