Buying a direct license is always better, since you can contact cPanel directly. I highly recommend using CloudLinux as well:

If you want some pointers, lmk. Ideally:
- Setup Proxmox
- Setup some VMs, maybe 1-2 cPanel servers for webhosting
- Only offer certain gaming servers, ie - Minecraft, CS, etc
- Don't offer anything Windows based - waste of time/resources
By downloading Tor and setting up a web server.
The official documentation recommends Apache, but it doesn't really matter as long as your competent enough to not get IPs leaked.
