> I also like to not create an account because I enjoy non-profiled search. I dislike getting served the same mush over and over.

You can disable Google's activity history, which includes YouTube videos watched. That should prevent personalised recommendations: https://myaccount.google.com/data-and-privacy

I disabled everything and can confirm that I only get garbage recommendations about things I've never watched or searched for.

That is true, but I don't think there is a necessity of having an account (aside from the EU forcing age checks) and I don't really want Google drawing conclusion about my viewing behavior either. I don't believe these options will prohibit Google from profiling you.

Definitely, it only disables the client-visible effects of tracking. But I don't think one can avoid the hidden part by watching without a Google account either.
