RESOLVED: I updated a device using Finder to iOS 14 and then connected to configurator which prompted a device driver pack download for compatibility and configurator now works for restoring and updating devices to iOS 14
After they fail the restore and loop back they need to be restarted for Finder to find them. Putting them in back into restore mode with press volume up, press volume down, then hold power while connected to the mac and Finder open was what did it for me.

Finder is unable to find devices - not very helpful
Use apple card
Unable to as now 2 devices are in restore mode and Finder on Mac cannot find them
I was able to resolve by plugging iPhone 8 Plus into a machine running macOS Big Sur beta 8. Music.app was then used to restore iOS.
