Most important thing is to make sure you develop the right habits so find a good teacher. Bad habits are easy to develop. Get fitted for draw length.
Other than that a good singel cam bow that has a forgiving 7+ inch brace height and is adjustable in draw length and weight is a good start. You don't need 300+ fps either though new bows reach this easily.
A great beginner bow that will do everything the high dollar bows will dois the PSE stinger or Diamond Core.
I like a trigger release myself.
