> The most common provider is cloudflare, but you need to install cloudflared on the machine you’re using to host

This is actually (strictly) true. You can use cloudflared on any system which can communicate with your host. This is useful in more realistic deployments as it means you can install cloudflared in a VM/container and then have it relay your services hosted in other VMs/containers/devices. It isn't helpful here as "I hosted my website on an iPad (but I now have to have this other real computer plugged in all the time so that iPad works)" is not as zesty :)
