Debian stable is a very solid choice for a server OS.
It depends on how you’re going to host your services though. Are you going to use containers (what kind), VMs, a mix of the two, install directly on the host system (and if so where do you plan to source the packages)?
I’ve kept my Debian system very basic, installed latest Docker from the official apt repo, and I’ve installed almost every service in a docker container. Only things installed directly on host are docker, ssh, nfs and avahi.
