Cloudflare takes a neutral response in general but are not resistant to law enforcement demands.
What you can do is to create a cloudflare account on Tor, buy a privacy-focused VPN that supports port forwarding, connect your server to the VPN and point the DNS record to the VPN ip address. And then create a port rewrite rule in cloudflare settings (because port forwarding supported VPNs rarely support lower than 1024 ports). Atleast in this case, law enforcement notices won’t be forwarded to your ISP… still not bulletproof, but good enough for most stuff if you have concerns.
It’s worth mentioning that this guy and the “Uber driver” works in the same company
