yt-dlp is great, but the setup is non-trivial, you have to save cookies in your browser and then put that into the command line. I have archived several useful playlists with it.

edit: have not checked recently whether there's a better user-friendly wrapper of some kind, so things might have improved since I last used it a couple years ago. Nuked the server it was on and forgot exactly what I did to set it up, and have not yet re-figured it out.
