StopTheMadness ($2) - This is a Safari extension (can also be used on Brave, Firefox, Chrome and Edge) that is mostly to stop various Javascript techniques to click jack or limit your experience. So things like preventing you from copying web page text, or when you click a link it also sends data to an analytics site. Also stops video auto play which is why I bought this extension in the first place.

Some web sites it kind of messes up though you can white list the sites. Problem is if you have multiple extensions it can be hard which one is breaking a web site.

Ghostery Lite (free) - Ghostery I've been using for years and Lite is the version they distribute on the Mac App Store (and Lite has enough functionality for me, I forget what it lacks compared to Ghostery). Ghostery Lite is an ad blocker and tracker blocker. Block lists update daily. Has limited configuration compared to Ghostery -- you can select categories to block and can white list sites.

Both together do make my web browsing a lot nicer. Not perfect but at least they're easy to use and free/cheap.
