I’m running Navidrome on my Raspberry pi (4). On my phone (Pixel 8) I use Symfonium to connect with Navidrome. When I’m travelling I use Tailscale + Mullvad + Symfonium to play music from my rpi.

Have you tried Tempo (FOSS)?

Forgotten apps: Lawnchair(Release) together with Arcticons. Very minimalistic!

Maybe you can try Discreet Launcher. It’s 1.41 MB.

Also the Phone app from Fossify has been released. Fossify Phone. Use Obtainium to download the Phone app.
