Masonry boxes for lights

I'm renovating a brick house and adding some exterior sconces. Seems like the only masonry box I can find is a single gang device box.

Is this what people usually use for lights or is there an octagon?

Also is there any reason I can't use a regular metal octagon in a brick wall?

Mason are going to want single gang rectangle, they’re easy for them to set in brickwork sideways.

It should be UL approved for acidity concrete conditions. But I have used a regular metal octagon box in a brick wall. As RC said the single turned side ways works just fine.
It seems most of the Octagon concrete boxes are designed for deck slab work. They are open like a box extension. You screw it to the pan. fill it with sand then put a cover on top like one end.

Per the UL Guide Information for Metallic Outlet Boxes (QCIT) all listed metallic boxes, other than aluminum boxes, are are suitable for use in concrete.
All metal boxes, except aluminum alloy boxes, are provided with corrosion protection suitable for installation in concrete.

Install the octagonal round mud box or whatever suits your needs. The masons should have no problem cutting the brick around any shape box. if they can't they need to find another profession or a corner to cry in.
