I am using a raspberry pi pico with a modified pico-cec program to control my Jellyfin-client media PC. CEC is actually really fun to hack on, and once you get a custom setup working, it is (at least in my experience) rock solid.

Jellyfin even has a TV mode that you can enable in a normal desktop browser. So my media PC runs the browser in kiosk mode, and it has CEC buttons mapped to keyboard presses. Guests have used it, and I don't think anyone could tell that it wasn't a "smart" TV.
