What’s wrong with F-droid?
Here's a list of URLs I have in #Obtainium if it helps anyone save time adding things. You may be able to import this list directly and just remove anything you don't want or need.
I'm gradually pulling apps from F-Droid and using Obtainium to update them. Thanks to nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z for pushing me over the edge on this.

It should be measured based on your personal needs or concerns, but I try to find balance with app sources. Here's some info on things to think about with F-Droid: https://www.privacyguides.org/en/android/#f-droid
