Cottonwood sure goes nuts on growth rate. What I've heard for intensive
silviculture with it around here is over by Paducah with Westvaco and down more
in SE Missouri. They're using irrigation and fertilization, which would help in
sand deposits after the floods. I think it could be done here as well
especially on islands and outside the levees. Everything else is farmed.
Distance to market seems to be a factor, but I'd think that barging would work.
Cottonwood has established easily after the flood, but I understand that it can
be a bit difficult to manage for natural reproduction since it's so intolerant.
I guess if you factor in that we seems to be getting five hundred year floods
every 5 years or so, you can count on a good seedbed, and a short rotation. :)
Plus as you say below, they're easy to plant from cuttings.

Firewood? I would think it would make lousy firewood, but then I'm used to oak
and hickory in the fireplace here.
Morels are the edible of choice in the bottomlands here and they're usually
abundant in the spring compared to upland sites. Would the others you
mentioned occur here as well or are they western species?
