Beginner One Shot Duets?

My wife and I want to start playing DnD as a way to host regular game nights and socialize with other parents in our community. I have only a little experience, and she has none, but we’re eager to learn. We’d like to play a couple short games together, just the two of us, as practice before hosting other beginners. I’ll be DMing. Anyone have suggestions for one shots or short games that might be helpful to learn on? TIA!
