I have oneworld ruby ( via AA Gold ). Unfortunately I can't pick exit row as I am travelling with my kid and elderly mom. I picked the seats below but not sure if "P" means the seats have good chance of getting reassigned? Cathay says,

"Cathay Pacific Airways has designed a number of Priority Seats on this aircraft for passengers who require special assistance. Any passenger assigned to this seat is subject to reassignment at the airport if such seat is required by a qualified individual who needs special assistance."
