I would suggest trying FreeTube and/or Invidious to watch YT videos. FreeTube can be configured in many ways and includes "Distraction Free" settings.
Both break every now and again as YT changes stuff, sometimes for a couple of weeks.
In such situations you can find videos with FreeTube and use tools like yt-dlp to grab videos.
But generally FreeTube works fine.
There are versions of FreeTube for the main desktop platforms as well as Android.
