The security "track record" isn't really much of a track record when you consider that their only claim pertains to "the default install" which frankly doesn't comprise a very useful set of tools for doing anything other than a router. But if you want a router, there's pfsense.
Anyways. My experience with OpenBSD mirrors yours. It's easy to set up if your desired end state is an X desktop and ethernet networking. 802.11 in OpenBSD is an exercise in patience to say the least, and the last time I looked (admittedly back in 2016 or so) most guides were still recommending wpa_supplicant and config file editing with a straight face.
I'm Canadian, so I really want to like The Little Canadian OS That Could but honestly it's second- or third-best at everything and best-in-class at nothing.
I don't know why a person would reach for OpenBSD in 2020 when Debian exists, except perhaps if you want to enable corporations to make parasitic profits from others' hard work. And even then there's FreeBSD for your playstation and for pfsense, and NetBSD for your toaster.
I dunno, it just seems like they make so much hay out of being secure, but the "secure OS" isn't much of an OS at all in terms of functionality.
