I highly recommend the DeArrow extension. I was on a waiting list after installing, for a few days, and then once I got access it has made the entire YouTube experience much better.

The extension removes clickbait thumbnails (replacing them with a part of the video itself), and clickbait titles are replaced with more accurate descriptions. It's all done by a big community, so the more popular videos are likely to have the edits, however overall it certainly is a better experience for me.
