TL;DR

Xiaomi has detailed a new tool called WinPlay which lets you locally run PC games on an Android tablet.

The app also supports games from the Steam and GOG stores.

The tool is currently available as part of an internal beta on the Xiaomi Pad 6s Pro tablet.

I do something similar and use syncthing to sync a folders on my phone to my server, I then use beets to manage my library (helps pull correct metadata) and jellyfin is just pointed to that folder. There’s a fork of the syncthing app on fdroid: https://f-droid.org/packages/com.github.catfriend1.syncthingandroid/
