People here seem partial to Jellyfin

I recently switched to Jellyfin and I've been pretty impressed with it. Previously I was using some DLNA server software (not Plex) with my TV's built-in DLNA client. That worked well for several years but I started having problems with new media items not appearing on the TV, so I decided to try some alternatives. Jellyfin was the first one I tried, and it's working so well that I haven't felt compelled to search any further.

the internet seems to feel it doesn’t work smoothly with xbox (buggy app/integration).

Why not try it and see how it works for you? Jellyfin is free and open source, so all it would cost you is a little time.

I have a TCL tv with (with google smart TV software)

Can you install apps from Google Play on this TV? If so, there's a Jellyfin app for Google TVs. I can't say how well the Google TV Jellyfin app works as I have an LG TV myself, so currently I'm using the Jellyfin LG TV app.

If you can't install apps on that TV, does it have a DLNA client built in? Many TVs do, and that's how I streamed media to my TV for years. On my LG TV the DLNA server shows up as another source when I press the button to bring up the list of inputs. The custom app is definitely a lot more feature-rich, but a DLNA client can be quite functional and Jellyfin can be configured to work as a DLNA server.
