Yoron, Zamami or Miyako?

I am planning to spend 14 days in Japan in October. I am considering staying only in Okinawa and visit Yoron, Zamami and miyako. However, I am a bit concerned that it may be too stressful and a lot of travel time .. I have been to Tokashiki and Miyako before, Miyako had amazing beaches and that’s why I would like to go back now that I can rent a car and visit it at my own pace. Tokashiki was also beautiful, and that’s why I am thinking that Zamami may be worth it … Yoron has been on my list since covid times, when I was exploring remote places in Japan on google maps :’)

Do you think it’s doable to do all three in about 12 days ? Would it be better to visit Okinawa island instead ? I have only been to Naha but now that I can drive I could explore more sides of the island
