Arch Linux is the closest I've seen to BSD in the Linux-verse. I recommend trying it. I'm not sure about production though, or using more exotic things like CUDA.

It really isn't. The BSDs are smaller and cleaner, especially OpenBSD, which is positively minimal. Arch is huge.
The closest Linux to OpenBSD is probably Alpine, of all those I've seen. Takes as much disk as most modern distros take RAM, and because of no glibc and no systemd, a tonne of familiar Linux tools aren't available or don't work... just the old fashioned Unixy stuff... which is very much how running a BSD feels.
