I used to use adguard home's docker container for it's DoH, but then a friend sold me on NextDNS. They all use pretty much the same blocklists, but NextDNS is much easier and very worth the $.

Bonus points to them because they also offer installers for Unifi gear so that your entire network can route all DNS through them, and its encrypted DNS! Unifi can even pass along the names of the devices.
