There are several blocklists specifically curated to adress the EU cookie nag:

AFAIK some prominent cookie notices are also part of the Fanboy Annoyances list: https://easylist.to/
The only prominent nags that are not very well targeted with those lists are in webapps like reddit mobile. Primarily because of their dynamic, non-descriptive ids.
