Videos from the well off people appear to be from Freeport area, where wind gusts likely 120-130 range, which would destroy a wooden house, but won’t do too much damage to a newly built concrete house. These people likely know their house can withstand cat 3 winds and stayed, probably to ward off looting.
My fathers house near Naples was hit with 140 winds in Irma and sustained minor roof damage and lost his linai. He could have stayed and been fine, but no power or water for weeks... New construction is solid.
