I do something similar with youtube. I choose a video from a content creator I like. For example vox or kurzgesagt. Then from the first video I choose I make a playlist with usefull youtube recommendations or search result to similar themes. What I want to say is to make a curated playlist is something that is made realy fast for oneself.

Spotify had once this killer feature that you could start a radio based on playlists. So i mixed some crazy playlists and the radio did get some interesting results. Something similar for video would be nice

Edit: there is something called couriosity stream. Its a website from some youtube creators. I gave it a try and it was nice. But many content missing
