NYC South Facing Patio Newb Needs Gardening Advice

I’ve got a south facing patio that gets full sun a lot of the day. I am thinking a mix of pretty flowers, vines that maybe hide the ugly railing, and things I’d eat (strawberries, broccoli, spinach, lemons). Above all I’m hoping for advice on what is somewhat beginner friendly and will last through the summer. Everything would be in pots or boxes (which I could also use advice on).
