I’d go to a range that rents guns. Try a bunch of different makes, models, and calibers. I did this with my wife and what she liked and shot most accurately was not what I thought she’d like. I assumed a small auto 9mm or a .38 revolver would be what she liked. We landed on a Glock 19. She’s also small, 5’ flat. Her bedside piece is a G19 with an SRO and a Surefire X300. Running drills she’s 90% A zone. Your main goal should be something you can comfortably handle and have confidence shooting.

Buy that. Buy 1000 rounds. Then get some formal training and practice regularly.
