In your price range you will get an entry level o/u or an excellent semi-auto. Go with the semi-auto. A Beretta 391 Sporting would be my choice for a do-all gun. But shotguns are a personal thing and it's your gun not mine. So go to a store, pick up and handle an 1100, 391, Browning Gold, Winchester SX3 and select the one that feels best in your hands.
