Do you use the flatpak version on Linux? I'm a bit of a noob but I think due to flatpak sandboxing it can't access your home folder or something, so I had this problem where it could only access my /media/ external HDD.
Aside from that, I just make folders named something unambiguous like "jellyfin documentaries", make a jellyfin directory from the control panel, name it something like "documentaries" link the two and then add the documentaries and then scan the libraries. (i may have misunderstood your question lol sry, English is my 2nd Lang)
Jellyfin, it's pretty simple and if you have a spare computer, a decent connection (and by decent I don't mean even a decent one by 21th century standards, I still have a 100/10mbps ADSL) and a 2/4tb Hdd, you can host your own FOSS Netflix/Hulu with all the shows you want, if you're in a county where "sailing the seven seas" is a huge deal, the only subscription would be a cheap VPN or even better something like real debrid.

how? most stuff is just released on streaming platforms, or on on-demand shit like that YT movie crap, owning stuff is more difficult than ever, the only real way to own your software/files is to pirate them, AKA making an offline copy.
