> I don't mind the 1 day wait too much.

I do. It's my device. And I've been in the position of having to buy a replacement phone in a pinch; having to wait an extra day before having a usable replacement is not acceptable.

In terms of apps I might not be able to get from the Play store:

- Signal, depending on what country I'm in in the future and whether they've tried to restrict things they can't backdoor.

- Vanilla Music, which remains the best music player I've used. (I wish there were an Android version of Quod Libet.)

- A fully capable version of Termux. (the Play store currently has a less capable version that's maintained separately, which could go away if someone decides to stop putting up with it).

- Syncthing-Fork, which has at times been undermaintained in the Play store.

I'm gonna try out Vanilla Music now. FWIW I use Musicolet from GPS and it's quite nice. I hope to learn whether and how our criteria intersect by exploring Vanilla....

Update: out of the box it seems to be reading tags strangely. Maybe I could fix this studying the settings more, but I'd say you have an upgrade opportunity switching off Vanilla. Signal is hard to replace though.

Honestly, the only thing I want out of Vanilla is the filesystem view. The only modes I ever use with a music player are to browse files as I organized them into folders, queue them up, and play the queue on repeat and/or shuffle.
