i wish there was a true android package manager similar to other package managers like apt and pacman for android APKs. there are a lot of apps such as firefox which aren't available in f-droid, which means you have to either download APKs manually or use the google play store, which requires a google account to be associated with your phone. there are plenty of APK mirroring sites out there, but the main issue with installing your own APKs is there's no easy way to update them. i wish there was a package manager where you could select your APK sources like with typical UNIX-like package managers, and then you could update all of them with one command. the main problem with this idea is it'd require large curated package repos to be useful, and android developers would have to be willing to submit their apps to them. the developer culture around android is much different compared to linux, as most people are only willing to submit their apps to the google play store without public source code. unfortunately, i don't think this idea could work.
