I used the cheapest wood money could buy at the co-op, twisted pine
It is soft yes, got a few decent dings from hauling gravel for my shop construction
The plan was to swap it out for better wood in the future
I suggest doing a test run of at least a few boards out of cheap pine in any event to get a feel for the order of cuts to make the little edges and how the boards fit
It will save you perhaps making a mistake with one or two expensive hard woods
