My advise to someone that has not shot a gun lots would be get a .22 and shoot the fire out of it. You can buy Bulk ammo at a reasonable price where you can shoot lots. Then I would try every gun in every caliber that I could find and see which one I liked best. What one person likes the other might not. The goal in the end is to have a gun that you like and can shoot well, because a miss is the same as not having a gun at all.
