I learned not to log in and use search wherever possible.
Now I use Invidious (with JS disabled and/or uMatrix blocking YouTube functionality in the browser as an additional nudge), or youtube-dl / ytdl / mpv to play video directly. Usually audio-only for talkpieces.
I'll also disable recommendations and comments portions of the website, for additional bonus (via Stylus).
I've been banging this drum for a while:
<https://news.ycombinator.com/item?id=6746731>
<https://web.archive.org/web/20160307214624/https://plus.goog...>
That references a G+ post which is of course dead now with that service. Wayback claims to have captured the post but I can't find a version that renders properly (or at all):
<https://web.archive.org/web/20131015000000*/https://plus.goo...>
(The HN submission referenced a post of my own on G+, which I believe I deleted shortly afterward.)
When I did utilise YT under a YouTube (and for a very brief time, Google+) account, I found the benefits de minimis. And in particular, what I'd most prefer would be to dismiss channels (or entire genres) with extreme prejudice, which simply was not available. And I'm not going to play rat to the Borg's Skinner box to find the reward morsel. I've got methods that work with ample sufficiency for me now.
So, no, not gonna bite.
Theres another script that deletes watched videos from the specific youtube plex library every night.
It works great as long as you remember to remove the videos from your watched later playlist before watching them on plex. (Have yet to find out a simple way to automate playlist removal)

It was (well, still is) a terminal-based YouTube client which provided search, locally-managed playlists, choice of playback mode (video or audio-only), downloads, and a number of other features. YouTube quashed it with an API-key limitations such that it is now effectively unusable.
But for a brief moment, YouTube content was accessible from a terminal window or console, without all the godawful dark patterns of the site itself. That was tremendously useful.
These days I'll snag videos by URL via youtube-dl/ytdl, and/or mpv (which invokes those transparently). Not quite as magickal, but still pretty good.
Hrm... Apparently there's a successor project, yewtube:
<https://github.com/mps-youtube/mps-youtube/issues/1191>
<https://iamtalhaasghar.github.io/yewtube/#installation>
I'm going to have to check that out...
Also I find it gives me a ton of recommendations for videos I've already seen.
The recency bias means that whatever terms you're searching become prevalent for that session. It's not possible to dismiss items or channels (idiotic on YT's part IMO), but you can at least create a short-lived preference instance unpolluted by any previous explorations.
