Don't know about customizability on MacOS but I've always been very accustomed to animations and recently I just turned them off on Android and Linux and I... Don't miss anything. Turned out they don't add anything other than an initial wow factor.

Personally, I think some animations can help add context to what is happening. For example, when using QuickLook, there is an animation when opening/closing QuickLook that zooms out from, and then back to the file location. If doing something with that file after the QL, that little visual clue helps find it faster and know where it opened from.

The closest thing you can do on macOS is to turn on "reduced motion". This doesn't remove any animations, it just replaces them all with fade animations which take the same amount of time.
