Recommendations for best hotel and beach on main island

Hi! I’m looking at booking our honeymoon on Okinawa’s main island.

Could I please get some recommendations for the best 5 star hotels and best beaches on the main island?

So far the Hyatt Seragaki and Halekulani seem to be good options but I’m wondering if there are others.

Where/what are the best main island beaches? Thanks in advance!
