In your shoes, I'd pick porcelain, and then get some ergonomic standing mats for work spots in the kitchen, if standing on such a hard surface becomes bothersome.

Grind, dye and epoxy.

I'm with the porcelain tile options...and G & S's option for stained epoxy concrete is a great one. The problem with vinyl in Hawaii is: vinyl HATES heat. Any heat. It hates sunlight (UV actually). It requires a stable interior environment (yep...even vinyl needs stable). In my experience as a sales person, the homes in Hawaii are often left open to the air outside (why wouldn't you?) to catch the ocean breeze. Humidity can be a major issue. And sunlight...they are Pacific Islands sitting around the same latitude as Mexico city. I think sunlight goes without saying.

I would look to porcelain tiles or finished concrete as your solution. Vinyl can have too many problems in "hot climate" settings.

What about cement tiles or limestone tiles? I would choose porcelain over vinyl, but I also like cement tiles and limestone for a more organic feel. We have limestone tiles in our mudroom and I think they're really pretty.

If it were my home I would use the porcelain.
