It weirdly didn’t break every website? It said it might, but it ended up not. No idea how, or what I did. The only issue has been my room mate plays mobile games and some of those give ads for a benefit, so they can’t watch those.

I’m using HaGeZi’s block list (https://github.com/hagezi/dns-blocklists). Not saying it’ll work for everyone, but it doesn’t cause me any issues, even on the strictest one.
