My sincere apologies, I have been wasting your time ! The Ubuntu and derivatives distributions that use systemd-resolved do indeed query the assigned DNS. I verified this by stopping the DNSMASQ service, which resulted in the loss of external name resolution. Turning the service on again restored resolution of internet domain names.
There is still an issue in distributions using systemd-resolved with resolution of LAN host names. As shown above resolution of a simple host name, in my examples BGOWIKI01v, fails. But when I add a 2nd name for that host to the /etc/hosts file on my DNSMASQ machine, with a suffix that looks like a domain name, like BGOWIKI01v.somedomain.local I can resolve the name correctly using the nslookup command. The solution for my reported issue will be to migrate my home LAN away an old-fashioned Workgroup model, to something that looks like a domain.
