Not commnenting on the efficacy of the following for everyone, but they help me:

Disable Autoplay for YouTube https://chromewebstore.google.com/detail/disable-autoplay-for-yout/dinkeiniijmpjehejhedbciaedblhnnk?pli=1

Return YouTube Dislike https://chromewebstore.google.com/detail/return-youtube-dislike/gebbhagfogifgggkldgodflihgfeippi

U-Block Origin, obviously (still works fully on Brave Browser) https://ublockorigin.com/

Untrap for YouTube (Block YouTube Shorts & Remove Recommendations) https://chromewebstore.google.com/detail/untrap-for-youtube-—-bloc/enboaomnljigfhfjfoalacienlhjlfil

YouTube Channel Blocker https://chromewebstore.google.com/detail/youtube-channel-blocker/ghpibapiigafgbaolopljimengkfjofk

YouTube Upload Time https://chromewebstore.google.com/detail/youtube-upload-time/nenoecmaibjcahoahnmeinahlapheblg

YTBlock - Block any content from YouTube https://chromewebstore.google.com/detail/ytblock-block-any-content/nedcanggplmbbgmlpcjiafgjcpdimpea

Some of these probably cross over in what they do, but I can’t be arsed delving into the nooks and crannies of them, so long as they do the job for me.
