contact groups in hostgroups versus services?

My suspicion is that in most networks, there are very few network devices that
have no services to monitor.  I only have a couple of switches that can't be
managed, for example.. those get a PING service.. everything else has
something I can watch, even if it's just checking SNMP to see that some
packets are flowing.

Yeah, that makes sense.  If your only service is checking ICMP, and that is
also your host check, then you probably won't ever get notified about the
service being down.  As soon as the service check fails, Nagios will execute
the host check, and theoretically that also will fail, so your host's
notification list will be...  well...  notified.
