I've used Plex for years, but Plex is moving away from being a platform where the primary duty is sharing your media library to having their own ad supported media, playing games etc. Apple has from the beginning kept your library buried under the computer section and that section is pretty bland. On a Mac your media does integrate in with your apple purchases. It still does not feed into the watch now like it should but its a start, I wonder if they will ever implement this on an Apple TV. I'm running an M1 mini as my server.
