I can vouch for Jellyfin - Nothing harder than setting up docker and connecting via Finamp. Been a very “set it and forget it” experience for me.

Oh well, off to the graveyard

For me the usb c to audio Jack adapters were a letdown. From the three I bought - all of them had a constant static noise. Especially hearable on lower noises. Don’t know if it was just the adapters I got, or if it was just a quirk my phone had, but I’ll stick with the dedicated usb jack for now.
