There is no need to have as little pressure on the shaft as possible, if you make the axle shaft strong and well supported. If the shaft is short and large diameter and well supported, it can take a lot of load!

could you list what you think are the pros and cons of both?

The neat thing about the wood chassis concept, is that you can build a couple of them, using different designs, for not much money. Then you can see how they work.
