In the better shotgun brands trying to decide between Browning and Beretta is a Ford / Chevy type of decision. Both Beretta and Browning make LH versions and with shotguns, it's best to try them both for fit and see what feels best to you.
Beretta make LH stocks and it would be worth trying to buy one with LH stock rather than one that is neutrally stocked. Some versions have a palm swell and if it's set up for a RH shooter it may not feel right to a leftie. You can buy LH stocks for Berettas from places like Cole Gunsmitihng or you could order a new shotgun from them with a LH stock.
As mentioned, Beretta have two choke versions, with the better one being the longer Optima choke. Browning offer similar choke systems. I'm not sure whether the Optima choke system is available in 20ga.
