Additions:
Add F-Droid basic as appstore. All the others are no stores as they either have too little apps, or none at all.
F-droid basic is modern and really optimized. If you trust the packaging, F-Droid is actually better than downloading random APKs that include whatever dependency that FOSS devs may get loaded in their Android IDE.
F-droid builds are reproducible. And also you can just use the app as a feed and add a ton of repos. Then copy the source URL and use obtainium if you want
For anonymization, add RethinkDNS and I2P. Rethink also has Tor, I2p is better for actually being anonymous.
For chat, add conversations for XMPP.
The mail client could be updated to thunderbird, it is already released with that Branding. Tough one, likely not your power.
Not sure if binary eye has QR code generation. This is what I currently use "secuso qr scanner" for.
For cloud, obviously Syncthing (maybe Syncthing-Fork, the main one is no longer maintained) as that works with no servers at all. And Nextcloud, which you can rent
For PDF, "MJ PDF" has more features and also uses Vanadium Webview.
As local music player, anrimians music player is nice.
In social networks, Grayjay and Jerboa are missing!
In Calendar, DAVx5 is essential to sync with a good mail provider. Not private at all though.
