Android phone (Pixel) question about Apps [View all]

This is a recurring issue for me, across platforms and devices. And I've yet to discover a simple process to achieve what I desire: when attempting to "declutter" a system, accessing the list of installed apps (or running processes, or whatever), what is the most efficient way to 1) discern what the thing is *actually* doing/needed for; 2) what are its co-dependencies ((ie, which things will break if I uninstall/disable/force stop it?) 3) who or what put it there and when (ie, is it legit? needed?)

Short of googling on the entry name and then reading through the results per item, has anyone come up with a more efficient way to do this? I can't believe this is an issue I still face.

Am particularly interested in android phone related experience.
