I don't think its as boolean as winning or loosing, i'm enjoying lemmy and haven't used reddit since :)

I use, Ublock Orgin(King), NoScript, Firefox containers, ViolentMonkey, Skip Redirect(I dont really like this but the ArkenFox guy recommends it), return youtube dislikes and Sponsor block.

I there any good learning resources for learning these things?

You can hide youtube shorts with Ublock Orgin's element picker :)

I think Disconnect and Decentraleyes do the same thing right? While its slightly worse there is a ublock orgin filter list you can use instead of clearUrls (https://raw.githubusercontent.com/DandelionSprout/adfilt/master/LegitimateURLShortener.txt)

I find the keepassXc extension isn't really needed since its got a pretty good auto-type feature built in

If you use firefox it already has a pretty dam good screenshot extension built in
