Congratulations on your news!
I would agree with Anne that perennial veg are great, they will tend to produce more in future years. This year it would make sense to minimise any potting on and transplanting, so short season, direct sown crops like peas and beans, leafy greens, carrots and whatever you know to be bombproof in your area.
