I think Arch is very close to the OpenBSD philosophy.

Not necessarily for security reasons, but more as a byproduct of keeping things simple so we can manage them manually.

I do not fully agree on this statement. Arch uses systemd which cannot be caled "keeping things simple" in my opinion. I think Voidlinux is a bit closer to what you description.

Void was created by a former NetBSD contributor, if I am not mistaken.

Xbps, its packager, is a breeze to use. And I've found no major qualms with runit, the init system.

Then use one of the derivatives. Obarun, Artix come to mind.

[raspbeguy]

I don't need to.
