It follows that an engine would run cooler overall if it is operated more efficiently. The more fuel burned, the hotter things get.

I tend to think the engine would wear faster running it at higher loads than normal. But then again, running higher loads and lower RPM would have the pistons travel less distance overall, so perhaps wear is approximately equal between the 2 styles of driving?
