I honestly have no idea. From my privacy research I found out Cloudflare is really unethical and so many websites use them.
Maybe some private alternatives here?

Yea, its the giant of the DNS resolver space.
I was hoping Quad9 may host DNS entries but it doesn't look like they do yet.
Ill look through this at some point to see if any are good. For now, https and authorization helps keep cloudflare from snooping too much, I hope.
