The more diving is clear
I will disagree with going to Key Largo and do guided dives. I would say go to Key Largo and do unguided dives. If you have a guide you are not doing dive planning, you are not learning navigation and getting to the boat on time, you are not developing self reliance, your focus is on following the guide. Do a couple guided dives if you want on the reefs, take a guide for a dive that is outside your comfort zone. But you need to do a bunch of unguided dives and the reefs of Key Largo are as nice a place as any to do that.
Also, just because you have done the 5 dives as part of AOW does not mean you have done everything in the specialty course. Over the years I have gone back and for fun retaken the specialty courses for every one of the dives I did for AOW. For most of them like DPV, drysuit, search & recovery, I learned a lot more in the specialty course. Deep not so much but I did my Deep specialty after over 200 dives because I needed the card for DM. We did 5 dives for specialty search over two days which was much more intensive than one dive with AOW. Same with DPV. With the specialty we got to work with several DPVs and much more intensive training.
