@Gargron I turn off watch history and only use my subscribed list. Turning off watch history seems to "break" youtube's homepage. You don't get algorithmic suggests and instead get a banner asking you to turn back on watch history.
I just scroll down on my subscribed list and work my way up on videos that I may or may not want to watch.
If I am feeling organized, I do that, but add the videos to a watch queue and work my way through that (removing as I watch).
Much better experience.
