Is there any that I should be looking into?

F-droid is the biggest one

Check out droidify or neo store for a better front end to f-droid

		I use Foxy Droid. It's unfortunate the official f-droid client is an unusable mess. (I stopped using it years ago, maybe they fixed it.) There's also f-droid classic, can't remember why I use foxy droid over it.

The Huawei AppGallery is hundreds of times bigger.
