Those are all good choices. Definitely stay away from the Country Squire type roof rails that were all the rage in the seventies. As said, these are not serious cargo carriers. But I have to say that the recent crop of basket-shaped, rounded edged carriers are not my favorites either for several reasons:
(1.) The basket length limits the length of the item you can carry. I cannot recall the number of times I have had something longer than the roof to carry, like a simple piece or pieces of lumber or a long tent pole. On the version I have, the top cross-bar is removable. So I can carry something longer than the basket without draping it over the end of a basket. In fact the version I have is completely configurable, and even disassembles into a box the width of the roof. I have used that to my advantage on several occasions.
(2.) The basket shape with its rounded corners and fixed sides, in my opinion, does not match up with the angular design of the Bronco. A matter of aesthetic opinion no doubt. But, a basket does stick out like a sore thumb more than a grill type. And few items that you will carry are round. Most often I have strapped on something long and quite square to the side bars and a rounded interior would have just defeated the purpose. Like an appliance box.
(3.) The baskets are all black and look like some sort of wrought iron grate stuck on the top. Again aesthetics, but, I don't know, just not agreeable to the metallic oragami of the Bronco. I would think that someone could get a set of the usual cross bars and design something more in keeping with the Bronco width and length.
Anyway, these are some of the things I had noticed over the years using the old, pre-basket design.
No? well then let me just say you've got a really sharp rig there and I've enjoyed checking out your pictures.
