Hey William, your list at the start of this post is quite rich and diverse. That level of diversity has been my goal for several years now and I currently grow around 300 species in my 0.5 acre urban garden. For the purposes of discussing a profitable crop for market which will grow in a mountainous woodland setting I would strongly suggest picking around three or four species which will be the backbone of our operation. This streamlines harvesting, drying, storing, etc. Looking at the most valuable crop per pound Panax quinequefolius (American ginseng) shoots to the top. But right behind is Hydrastis canadensis (goldenseal). They will both grow well in the dappled light of the forest. Look for areas with maple and poplar as the canopy and rattlesnake fern as one of the perennials. These tend to be indicators of a good place to grow American ginseng.
In the mountains you should be able to grow Angelica archangelica quite well which is another wonderful herb, primarily for women. It is a valuable market crop but, I believe, acts as a biennial so a cycle of seed collection and germination might be in order if natural reseeding didn't establish. Also, I see you already have cohosh on your list. That's a great one as well.
You might find that with those four you could provide a reliable income (once colonies are robust enough). And picking just a few to take to market makes the project much more feasible. Try to juggle too many crops can undermine a small farming operation.
In the Black Mountains near Burnsville, NC is a farm called The Mountain Gardens. Joe Hollis grows around 500 medicinal herbs and has done so for decades. He sells seeds, plants, gives lectures, hosts interns, grows food, keeps ducks, etc etc. He might be a good resource for you as you move forward.
