If you’re meeting them for the first time, then alcohol seems a bit low class. You sound like you’re proud of the fact that you snagged a rich girl, and need to bring your A-game.
I suggest quality tea or coffee. Maybe even coffee beans along with grinder or roaster or something along those lines. A nice pair of socks is always appreciated. A tasteful scarf that you picked out to show you took time out of your schedule to be thoughtful and it will show how discerning you are in your tastes....e.g. are you in the same class. If they have a dog, a smart collar would be appreciated. If she’s Asian in addition to presents bring good quality fruit to give to the matriarch of the family. Find an Asian friend to help you select. If she’s white, try virtue signaling. Like if you have Native American or Latino in your family, let them know that. But if they’re racist or republican then buy something nice for her father’s gun collection if he has one. Overall, parents just want their daughter to bring home a good guy. If you’ve hurt women in the past, then your character will shine through at some point. Your gifts won’t matter. Be moral, be kind, and don’t procrastinate and show up with cheap gifts or gift cards.
