LFS/BLFS. Which BSD has that?
I don't disagree with you fully, mind you, but I think this is mostly because many more noobs use Linux, whereas on the BSDs more people with a lot of knowledge use it. But even then I would reason that there are more experts using Linux than OpenBSD, simply due to numbers alone. Not all of them can be bothered to write blogs either. (And sometimes they have reallife hardships suddenly, such as Fefe.)
There is a reason the top 500 supercomputers all run Linux. No BSDs there.
Surely any BSD is "FS" being a fully functional core system from one source tree?
> LFS/BLFS. Which BSD has that?
They can’t have it. The BSDs are a complete system, where the kernel and utilities are built in sync. And building them is quite easy.
Linux complexity may give you flexibility, but most users systems are fairly simple. OpenBSD has a lot of documentation, and if that’s not sufficient, you browse the source code to see what’s happening.

That comes with the system. Here's the manpage: https://man.openbsd.org/release
