I respectfully disagree. I have very little Linux/Unix/xBSD maintenance knowledge, but I started running my own server for my personal email and website. Although I used a script as a crutch to set things up at the beginning (thanks to sive.rs/ti), when I started digging in how things work - and when I eventually run into some issues like expired certs - I managed to understand things much faster than when I was trying to run a server before with Ubuntu.
For example, Googling things are easier since the tools don't change much over the years, so an answer from 10-15 years ago still works. Besides that, I could find most of my answers in the very well written man pages. There's also just fewer things happening so there's not much clutter to distract me finding the answers I need.
I'm still a beginner of course, but I feel like OpenBSD is good for any application where you need to run something and then "forget about it" - be it a server or maybe even a "kiosk"/informational screen.
