Got it.

I'd checked the fuses but admittedly did not pay attention to fuses that were not obviously a part of the systems affected.

This morning I said screw it and pulled every single one and put it under a microscope.

Found one that to the naked eye didn't look blown but on closer inspection it was.

It was labeled "Meter" which obviously means Instrument Cluster.

Replaced it and everything came back online.

Apparently without a functioning instrument cluster the starter solenoid won't fire and if you jump the starter solenoid to get it running the transmission does not know which gear to select without RPM and Speedo input so it defaults to 4th gear.
