I'm not sure why it's significant that you'll be moving to Hawaii with your bike--a road bike is a road bike, no matter where you go. If you think you'll want to ride on dirt roads and trails, you want to think about something other than a road bike.
Having said that, it sounds like you have some definite ideas of which bikes you're interested in, so my best advice is for you to go to a bike shop and try them all out--see which one feels best to you. It's a very personal decision.
