I believe ytDownloader might be what you’re looking for. It’s a yt-dlp frontend, you can export to video/audio pretty easily. And it’s in active development. I’ve used it to export short clips to WAV a few times, nothing too fancy, but so far it works pretty well.
For those on the fence about Borg Backup because it’s a command line app, FYI there’s a great frontend GUI for it called Vorta (yeah, in line with the Trek theme lol) that works really well. I don’t see it mentioned often, thought I’d pass that along. Might want to avoid the Flatpak version if you need to back up stuff outside your /home dir.
