Seriously, exactly why did you not suggest f-droid as well?
Probably because it's kind of a bad experience? I say that as someone that uses it regularly for multiple apps. I'm not a fan, the search alone is basically useless unless you know the exact title of what you're looking for and even then it's sometimes not the first result for some reason.
I'm sure that someone will reply to this with some suggestion for some alternative front end for the fdroid store that supposedly fixes that which will just further highlight the issues with it of fragmentation
Okay, yeah, that is definitely a valid criticism. I have noticed that myself.
If you visit the grapheneos forum, it is generally not a preferable choice, for security reasons.
Yes, because it makes a few sacrifices in order to allow you to have your own repositories such as certificate pinning, which honestly, I'm okay making those sacrifices because with things like accreacent It's nothing but Google Play by another name and another company or whatever, because a government can go to them and require them take down an app where that cannot happen on fdroid, because the developer can just throw up an onion service and host their repository on that.
Looked at first minute, seems to be about GrapheneOS. Talks about privacy, might be worth watching, doesn't obviously drag. Around 11 minutes long.
Graphene os seems to be a popular option. For some Sonys you can install Sailfish. Any other options?
Depending on your appetite for such an experience you could look at PinePhone or FuriPhone or some of the other "linux" ones.
