Anyway to 'browse' metadata to figure out how to name something properly?

You have to go to your primary metadata source and just kind of figure it out. Some shows only have 1 or a handful of specials (Violet Evergarden, for example), some have dozens and dozens (like my Shakugan no Shana example).

Another personal example that required a lot of manual work, the original 5 seasons of Futurama. The DVD source media has a MASSIVELY different order than what I wanted and was used to. You just have to set the file names according to the order, which may require you watch every file. If your media has the episode name, that can definitely help.

At the end of the day, if the order you want is different than the order you have you just have to figure it out. Jellyfin nor Plex nor Emby has a way to figure out what you have. YOU tell Jellyfin what you have and Jellyfin has mechanisms to adjust which order it queries from TMDB/TVDB.
