Bulkhead row 23 is good. Emergency exit row 35 is even better. However, don't expect to get it simply by request. Bulkhead 23A and 23L are basinet enabled seats reserved for mothers travelling with infants. The rest of row 23 is reserved for Club 2000, FPRouge, FPBleu, and other High Contribution passengers. In the event that there arent any, then give it a shot. There are also bulkheads on row 36EFG, however 36E & 36G are basinet seats, and are reserved for mothers with infants. In the event that 36F is empty, I doubt you'd want to sit there, with 2 infants on either side of you.
Emergency exits are reserved for very tall passengers, and are sometimes given out at the gate. Unless you're over 6'4", I'd advise you to ask at the gate. Whatever you do, don't sit on row 31ABC/JKL or 48 AB/KL, no recline whatsoever. Best of luck.
