You probably don’t need one, but it’s nice to have the option
Don’t even need your own Certificate Authority - get a public domain and do a wildcard sub-domain from let’s encrypt.

I mean you could already with a custom DNS server and internally controlled CA. Honestly IP certs are extremely bad unless you own the specific public IP block. If you’re borrowing an IP that’s registered to another company, even if you have a “static” IP, it risks being changed and you can’t port it somewhere else. Don’t even get me started on DHCP for internal systems.
