Welcome and congratulations. Lotta fun, and you sorta started right in the middle and did well enough it seems to me.
I would agree that a .22 (.22 Long Rifle cartridge) is probably the way to go. I sorta like revolvers for a first handgun for folk, but, the semiautos, even the less expensive namebrand ones, are generally all so very good today I wouldn't blame you for going for one of those...
Do take the NRA Basic Pistol class, at least the First Steps class -- you'll feel better and sort of liberated from all the opinions that everyone in the world has many, many, of.
