Either PF or IPFW, depending on who you ask.  Or, if you work for Juniper,

I used IPFW for many years, now have used PF for many years.

Which of them, if any, have FW for dummies like tools/guides?

Peter Hansteen has at least one famous book on PF. There are example IPFW
firewalls in /etc/rc.firewall, too.

IPFW, IPF, PF. Three firewalls in only one system. I hope one day there
will be a consensus to keep only one.
