Highly recommend Quad9. Their privacy policy is absolutely no identifying data logging, period. They're also the few providers offering DNS over TLS. Google, on the other hand, keeps identifying logs for 24-48 hours.
Just watch out for them if you're not in the US - any DNS-based CDNs will send you to an American node rather than your closest, it could slow things down a little
