Have you ever ridden a stiffer freeride board? How did it feel? Your feet are pretty small, so you really need to be careful with waist widths. I am about your size, with a size 4 boot, and my toes end up being too far from the edge of my board to control it very well. The stiffer the board, the harder it will be to control. The compromise for a light rider with small feet is to find a good combination in a freestyle board of easy turning and stability. For me, that board is a Never Summer Pandora - soft and easy to turn, but still very damp and stable for all-mountain riding. It floats well in powder and have vario grip edges for ice and hard pack.
So from your list, the Farah would be the riskiest board to purchase. It is an aggressive board, but it may be too stiff for you to be able to turn with your small feet. The Feelgood is a better bet. Also look at the Never Summer Infinity, which is similar in terms of stiffness to the Feelgood.
