Just to update this thread: the issue is now resolved.
After further testing, internet connectivity started working normally on the LAN without any changes to the OPNsense configuration. At this point, it looks like the problem was not related to the OPNsense setup wizard.
We suspect the issue was related to our lab environment, possibly VMware Workstation networking or another temporary issue in the lab setup.
Thank you to everyone who took the time to read and assist.
