Subtitles would be excellent, but in my experience, they’re much easier to set up when making an edit from scratch. imunfair from r/fanedits made an automatic subtitle script, though, which takes in subs made for the unedited content, and changes them based on the edited version - caveat that it only works if you’ve been editing in Premiere Pro.

That said, Premiere Pro does make working with subtitles pretty easy, since you can move them around in the same way as moving clips or audio around, and you can edit the subtitles within the program.
