What are the better solutions that you’re referring to? I’m setting up monitoring at work now and want to make sure I hit the target with whatever I put in place. Right now I’m dabbling with Prometheus and grafana and it’s been decent so far.

you’re not wrong… but you gotta give credit where credit is due. Plex does a good job of having a client on every platform. Telling family and friends “search for plex on your devices app store” is a whole hell of a lot easier than having them jump thru all the hoops that it takes for jellyfin to work.
