Just to close the loop here - following @jimp's instructions, I was able to install with Recover Config as advised. However, if I had it to do over again, I would have tried to install with 2.4.3_1 w/Recover and then upgrade vs. 2.4.4 w/Recover because the resulting install was very slow and became non-responsive whenever it brought up the WAN interface and while the install removed some packages, there were vestiges of the old settings in places like the Services menu and on the Service Status widget on the dashboard. Unfortunately, it doesn't appear that the 2.4.3_1 disk images are available anywhere.
To resolve the slow WAN issue, I inspected the config diffs that the install/upgrade recorded and notice "an unknown interface change" - it turned out that advanced DHCP settings were enabled for the WAN interface with none entered so I disabled it and that seemed to solve the WAN access and performance issue.
To eliminate the package vestiges, I installed the various packages and then removed them to purge them fully. I probably could have downloaded the config and removed any semblance of the packages instead but wanted to rely on more supported methods.
The system seems to be working properly now and I really appreciate @jimp's prompt insight, help and guidance. Rock on!
