The only thing that makes me think it’s NOT the sensor is that the lower thermostat hose is still ice cold after running for 10 min. Realistically it should have opened up by then and flowing warm coolant

It it should have opened ? Yes if it’s not your water pump it’s your thermostat if no air in system. What else could it be ??

I run an in-line thermostat on the Rover with no bypass path.

To run without thermostat you must block the bypass hose. Inserting a golf ball in that hose worked great for me 50 years ago on my '68 BMW. Coolant flow must go only from engine block to radiator inlet, and radiator outlet to coolant pump suction.

The OP just did his head gaskets. It's possible some junk got lodged in the stat...but I'm betting, front up high on a steep incline would help.
