I don't even understand what this feature is supposed to be. All I know is that the share screen _used to_ work really well! It used to show my most frequently contacted friends / family across applications (eg. Whatsapp vs Hangouts vs email) and it was a breeze to share content. Now... It shows the correct contacts for ~1 second, enough time for my brain to think oh maybe I should try and oh nevermind it's gone.

iOS actually isn’t much better here. Occasionally I’ll see something on Apple News that I want to share with friends who don’t use Apple News. I just want a web link. But despite Safari being literally the only icon I’ve ever tapped on to share something from Apple News, I have to hit the “...” and then scroll to find Safari buried in the list. I have to scroll past Strava despite (as far as I’m aware) Strava not even being able to open the link and me never having used it to open the link.

You can change the order of share items.

When you are in the “...” screen, tap on “edit” at the top right.

This is what OP complained about is not possible on Android out of the box.

iPhone has the same issue in something simple as recent contacts / phone dialer screen. I end up clicking the last dialed number that gets replaced on top of last-but-one by the time my finger moves to tap what appears as last-number, which was really the last-but-one, but the history wasn’t updated then.

My least favorite android UI feature is the "clear all" option on the list of notifications. Every time I use it, they randomly show up again hours or even days later.

That's a bug/feature of the application(s) offering the event. They get an intent informing then that the notification was dismissed. Well-behaved apps should not repeat the same notification later on, but many seem to do when an additional notification comes in. :-(

Thanks, that makes sense, but also makes it even more annoying when default Android apps behave that way. :|
