Barrel wall thickness will be the deciding factor. You can call Stu Wright and give him the appropriate barrel dimensions, and he'll say yea or nay.
I've never seen a Beretta fixed choke gun with enough metal to allow "standard" chokes to be used. Chances are you will have to go with a thin wall series. Briley does a good job with these, but be warned. If your barrel walls are at or near minimum thickness for the job, you may see threading bulges on the exterior.
Talk to Briley about this. If it were my gun, I'd have the chokes opened and leave it at that. What you pick will be determined by where you shoot. Personally, I'd pick Improved Skeet and Modified. If your courses are longer, maybe Light Modified and Improved modified.
While you are thinking about this, I'll tell you a story. When I bought my new 20b gun, I decided to got to a Sporting training class. I went up to Woodcock hill. Two instructors were assigned to me for the entire day. The shooting Instructor insisted I put in my two most open chokes. I cheated a bit and put in LS (.002") and IS (.007"). I spent the entire afternoon breaking targets with those chokes, including long right angle crossers 45 yards away. They were good breaks, not chips. That experience taught me I did not need the amount of choke I normally put in.
