To me, all of your border options detract from the beauty of the main part of the top. You haven't mentioned how you intend to quilt the top, but here's what would appeal to me. I would add the narrow gold border of option #5. then I would add a single wide border of rust or green. Then I would quilt that wide border with the design that's shown in your border design of option #5. That would then carry on the design of the main part without detracting from it.
I guess I'm in the "sometimes simpler is better camp".
Whatever you decide, it's going to be a beautiful quilt.
