I used ddclient with Cloudflare for years with no issues.
Recently upgraded my home router and the manufacturer operates a free dynamic dns service enabled with a toggle button. I have a cname record in my domain’s dns records pointing to the dynamic dns entry. I actually don’t even need that anymore. All the services I run at home are only for immediate family so only available remotely via a Wireguard vpn connection. I migrated that to the router also because it can do 900Mbs of Wireguard traffic and has a great vpn server management implementation. By default the client configs it generates points to the dynamic dns name. No real need for the cname but I have it out of habit.
