I get around this by not using dogshit platforms.

Firefox has an option called copy link without trackers on their desktop version which covers a lot of this.

For anyone who wants to take this seriously but doesn't know what to do:

TL;DR: Chop off everything after the question mark.

Usually these trackers are at the end of the URL, after a ?. That's called the "query string parameters" of the URL, and it's where developers will attach extra information for the server or page. Often, those are benign and useful: It's a token that identifies you to the server, or it's context about what you're trying to do. Sometimes you can eyeball the query string params and guess what they do, e.g.:

coolvideos.com/videos/5432?fullscreen=true&autoplay=true&time=12021

or

cheapshoes.com/search?query=adidas+tennis&category=womens&filter=discounted

or

https://m.youtube.com/watch?v=dQw4w9WgXcQ

If you chopped off everything after the question mark, the URL should still work, it'd just give you a default version of that page. In these examples, there would be no privacy risk to sharing the URLs somewhere.

But query string params are also where alot of marketing/tracking bullshit goes. When you see URLs with UTM params like "utm_medium" and "utm_campaign", that's marketing bullshit. They can also contain info about who you are, like what OP is describing: If it's some kind of referral link for example, then it might look like pyramidscheme.com/special-offer?associate_id=455&source=facebook. It might be esoteric too, like the "igsh" param in OP's post (which I assume is short for "Instagram share" or something?). That WOULD be a privacy concern.

So yeah... Often you can eyeball it and figure out what (if anything) to remove... And if in doubt, try chopping off the question mark and everything following it, and see if the URL still works.

Pretty much every site on the internet is using tracker links at this point. And many times they won't even be visible if you click or hover on them.

For instance, on Facebook literally any link you click will look like a normal link but when you click on it, it sends you to a tracking domain at l.facebook.com. I just blocked the entire domain. If there's an Instagram or YouTube video posted it'll actually hide the link altogether, and even the title, so there's literally no way you can reach that content without going through their tracking service.
