Check out pinchflat. Think of it like sonarr for yt channels. I use it to grab content for my kid that he consumers via Plex so I can limit what he sees and remove the algo.
Pinchflat does all the renaming, metadata, and file structure as I configure.
I wish it supported other sites that yt-dlp supports, particularly Nebula but this is already a great start, and hopefully they'll add other sites eventually. It seems this has been discussed before.
