Solution
As pointed out by @Vittelius@feddit.de here comment, and @iturnedintoanewt here, one can manually identify a show by clicking on the 3 vertical dots in the corner of a movie or show when hovering over it, and click "identify" (you must be logged in as an admin account). One then simply fills out the fields, as desired, to find the correct media.

I have a few shows that Jellyfin isn't able to fetch the proper metadata for; they just display blank in the listings with only the original filename. Is it possible for me to select that show, and manually override Jellyfin to identify it as a specific show without renaming the actual file?
Whilst you can override it manually, I heartily recommend modifying the folder/file names so that autodetection works correctly.
Otherwise you'll end up just manually fixing it again next time there's a significant library change.
