Yt-dlp is great! I used it it to download podcasts from Youtube so I could listen on my phone. Only later I discovered I can download straight through Pipepipe(youtube client). I actually even used it shortly for regular videos as well to watch them through VLC just so at the end of the day I wouldn’t get hooked on youtube shorts and the rest of the nonsense on the front page. Yt-dlp also works for most social media sites. X, Tiktok, etc… Not sure about the value of downloading videos for the sake of storing them (after you’ve watched them) tho. I rarely rewatch videos.
