I would suggest taking a NEW skill class. As you are AOW I suggest Stress and Rescue. If you have some recent dive experience but feel a little rusty, then learning something new and engaging with other divers and instructors will be a great immersive opportunity.
Most Stress and Rescue classes bundle First Aid and CPR and we call all use a refresher on that once in a while.
