There's a great Safari extension for this called Hush[1].

After installing this, I rarely see any cookie popups.

And this https://www.i-dont-care-about-cookies.eu/ for a number of other platforms like Firefox and Chrome, and it's recommended by Firefox.

uBlock Origin will take care of blocking tracking popups/banners for you if you enable the "EasyList cookie" filterlist in the settings. It is not activated by default.

My life became so much better when I activated EasyList. Makes me wonder why is it not activated by default.
