The OP knows very well how to halt a system as he posts a list of
several ways of doing it. Each one valid.

He is asking for a "preferred methond of shutdown of a Linux Sever".
IMHO my answer tries to show that there isn't a preferred method. It
depends on how those commands are implemented.

Checking his distro's *man shutdown* is a good advice IMHO.
