Current Ford guidance is to return the front height HALFWAY between unloaded disconnected and loaded connected with spring bars. IMHO, the closer you return the tow vehicle to level, the better. 1/2 ton trucks are designed to be tail high when unloaded. Unless radically angled front high from the load, I'm not sweating the headlight concern. Otherwise, truck makers would have headlight auto level systems installed for differences between unloaded and fully loaded states.
Wheel well measurements are not needed, the OP already has actual cat scale numbers. An adjustment to his hitch, as others have mentioned, is all that is needed to move some weight off the rear axle and distribute it to the front of the truck and back to the trailer axles.
