Yep, you basically just described the setup, nothing super fancy :) Cron job which runs a batch script at midnight which feeds youtube-dl some playlists URLS's which it downloads to a HDD. I also have nextcloud running which has access to the directory the videos are saved to, so I can easily share them if I want to.
