For YT, try a client like NewPipe or SmartTubeNext that can be configured with adbock & sponsor block, and which is less "in your face" about suggesting/autoplaying rabbit-hole content.
Considering NewPipe isn't available in the Play Store or at all on iOS, I'd imagine the number of people using it is small enough that Google doesn't care too much.
Technology-wise, NewPipe builds off of the back of youtube-dl and a custom page parser, and SponsorBlock uses a user-built database of timestamps.
