FWIW, Lidarr works the worst out of the arr stack for me too. I don’t know if there’s just not enough well indexed material in my sources or what, but yeah, not great.

If your entire experience with the arr stack has been Lidarr so far, give it another shot! Sonarr and Radarr work absolutely perfectly. It’s just such a nice feeling to open Jellyfin (or I guess Plex) on the TV and go “oh nice new episode is out!”
