Don't get too crazy into categorizing your media. Keep it simple with your folders, so Jellyfin can know what the file is then scrape the internet for meta-data.
Media -> Movies -> Example Movie (year) -> Example.movie.file
Media -> Shows -> Example Show (year) -> Season 1 -> Example.show.S01E01.file
Ideally your media downloads will have the name and release year in the folder name already. It knows to ignore or match things like x264, DD.5.1, and release group name.
