Leave the U last if you have a wide forefoot. I have some, we're about the same size, and the wide width on U is OK across the ball but then sloppy in the heel and instep.
Get the F last in a 43G (wide). 43.5 will probably be a shade long. Go for the dark gold or brown museum, or for something more classic, I can strongly recommend oxblood or dark brown. Both the OEII and French Oxford are gorgeous. Get one of each.
