High grip means high wrist, meaning the bow is meant to be shot with the throat of the grip in the web of the hand between the thumb and forefinger. The heel of your hand is pretty much out of the picture, revolved out of the way. Can't really place the heel down on a high wrist grip.
Beginner to intermediate classification is good marketing. Covers just about everyone, don't you think. Aren't really very many expert shooters around regardless of how long they've been shooting.
With a 28 1/2-inch draw, that bow will stack on you. You'll also feel the finger pinch. At 40#, it might be bearable. Certainly don't need a bow that short, or a shorter bow at all, for hunting. But, whatever floats your boat. Good luck.
