I’m just not sure what to do with it yet. Think I should talk to an architect?
You don't have to think of anything to do with it yet, slow down.
Isn't a large paved area a good place for Antonio to ride a bike around, or bounce a ball around, like in a game of mini-basketball, with some friends, at least for the time being?
Settle into your new home first, there's plenty of time to talk to an architect-- hopefully you'll be in that home a long, long, time. The longer you're there, the clearer you'll know what you want, and, need, in terms of your outdoor space.
