Welcome aboard. The best thing you can do is if your wife does a desk job is to also get them a board. My wife has the exact modded GMMK 1 Full Size as I do, but with XDA Godspeed. She uses it every day and can "feel" what I feel when I talk about the typing feel of a mechanical board. My other suggestion is to start small so you have room to grow. Get a hotswap board with a layout you like, then try new switches and keycaps until you find exactly what you want.
