I started on a list a while back and quickly found that when you don't factor in banking apps, the majority of other apps work without any problems. Some rely on Google Play, but they usually display a helpful popup saying as much.
Since installing GrapheneOS and becoming an active member of the community two years ago, I have only known of two apps that just won't/wouldn't work (I'm not counting apps that refuse to work because of Play Integrity, I mean apps that just won't work).
There's also the fact that maintaining an app compatibility list would be a lot of work.
