The initial cost of diesel isn't a problem, but what about long term maintenance and operation costs. Most of my daily driving is quite quick and short. I'm worried that diesel engine will only rarely get the full workout.

7.3 engine with 4.3 axles, 7.3 engine with 3.73 axles, or 6.7 diesel with 3.55?

Gas 3.73 and Diesel 3.55 save most on fuel.
Gas 4.3 is the most I really need.

Emissions controlled diesels do not like short trip use. They need long runs on the highway, or your ownership costs will escalate.
General cost of ownership is higher than gas because diesel has been higher than gasoline for some time and you'll need to feed it DEF. Fuel filter changes are more frequent and more costly. Oil changes about balance out with gassers.

There are many more comparison, both good and bad, but primary short trip use and lifetime truck are nearly mutually exclusive in a modern emissions controlled diesel IMO.
