A few nice things about the Bike Friday. It is one of the lighter cargo bikes, but everything I've seen indicates they are quite robust for regular use. I'm not sure how that compares to the smaller cargo bikes like you've found.

It is a small USA company, and they'll make the bike to your specs, although not necessarily cheap. So, for example if you wanted drop bars or touring bars, they'll add them. For some bikes, they'll send you an adjustable stem, then once you get the size set, send it back and they'll custom fabricate a gooseneck stem.

They used to put the DualDrive into some of their bikes, and could put in other IGH hubs if you needed.

Plus a color choice.

It sounds like Workcycles, above will also do some customization.
