Hi Dawn! Welcome to NGA and to gardening! Congratulations on your now-deer-free yard!
I guess some people DO plan ahead, but I've never been interested in making people gasp at my garden's artistic merit. A good thing, too, because I have about as much artistry as I have wings. But I love watching plants grow, which was my second ambition after "watching plants NOT all die".
I lean towards vegetables, and it might not be too late to throw a few seeds here and there, just to see what comes up.
One handy place to start, to get an idea of "what's in season", is a generic planting calendar that knows your ZIP code so it can figure out first and last average frost dates.

It's not too late for lettuce and spinach! I see it doesn't recommend fall peas.
