By domain its actually the people who control the domain .us domain information not cloudflare. Cloudflare has been my goto for a number of years they do a good job masking the information and once you set those settings they do not change them (I am looking at you GoDaddy). I will second Porkbuna nd Namecheap as good options.
I want to second Dokuwiki. It is a step up from text files in a folder, easier to install and maintain than Jekyll (I am a big fan of Jekyll but have a deep-seated hate for Ruby). When compared to all the other wikis it is by far the easiest to install, maintain, and move to another server.
Dokuwiki is all text files and a version of markdown, the files can easily move to another markdown system.
I have two piholes setup as full recursive dns servers (unbound) DHCP is handled by TP link Omada and the piholes are the two dns servers. The top of the DNS chain is cloudflare 1.1.1.1
