I have one folder for movies, one for kids movies, shows etc. It takes some work, but for sorting similar titles I just click on the show and edit the meta data. There’s “Title”, and “sort title”, so in the case of Star wars and its sequels I leave “title” for Starwars, empire, and Jedi the same but change “sort title” to starwars1, starwars2, starwars3. Same goes for Harry Potter for the kids, or anything in a series with a subtitle rather than a number.
I got a raspberry pi and some wd red drives when Google photos went for a pay model. We use it to back up our phones and pc, and to run jellyfin and torrents. It’s not wildly different from doing things on pc, except it’s set it and forget it. Having something always on, reliable, and “just works” makes it worthwhile.
