Have you tried Lulu or Little Snitch?
I've used both on various versions through 10.14. It is my understanding that due to Apple exempting their own software from the Network Extension Framework, both are hobbled on 10.15+, but that with 11.2 they will be reversing that choice.
My issues with modern macOS for server applications are mostly with the broken logging and the difficulty of stripping down the operational environment to just what's needed on a Mac that doesn't normally function as a personal computer.
Disabling the built-in firewall entirely may be your only solution. I am not sure because I have not bothered trying to make any macOS newer than El Capitan usable as a server. Life is short and FreeBSD exists.
