I have the Easylist one enabled, is there a more reliable one?
It doesn't catch them all, especially more niche sites that do more custom stuff to prevent you using the site until you interact with the notice. e.g. screen overlay, prevent scrolling using css rules.
I have the 3 default "annoyances" listed enabled, ublock, easylist, adguard. I rarely see cookie popups. Notably, youtube's cookie popup still appears, but probably there's a reason for it. So, you're right, however for me it's good enough.
