No, it isn't normal.
Thermostat is good to change but stick with stock 190-195degF model, it will make engine last longer, and get better MPG.
Ford temp gauge is about 210degF at 1/2, so in normal operation it should be just below 1/2, when pulling a load or driving up a longer hill it should go just above 1/2, 220-225degF
Running an engine cooler may sound like a good idea but if it was true it would be very very easy to run an engine at 100degF, problem is it isn't good.
Point of the thermostat is so engine will run at a higher temp, after many years of research by S.A.E.(the oil guys) and Ford, the 195-200degF coolant temp range was found to be the best for normal operation, cleans the oil better(evaporates contaminants) and gives cylinders best temp for MPG
Your Fan clutch or radiator could also be the problem.
After engine, and rad, is warmed up shut off the engine.
Spin the fan by hand, it should be tight, and not spin after you let go of blade, it will turn just not spin free.
Now remove the 2 bolts holding top of fan shroud, lift it and slide it back over fan.
Run you hand across radiator fins, top to bottom and side to side.
There should be no cool spots, should be nice even heat across and down, a cooler spot means no flow so clogged area.
Also check front of rad, clean out any mud, dirt, or debris.
