One cup, side by side
Does bread flour weigh the same as all-purpose flour?
By weight per cup, yes. King Arthur lists both at 120 g per cup, so dishscale converts them identically — the two are different flours that happen to fill a cup to the same weight. If you have a published source that separates them, that is worth sending in; the figures here are meant to be checkable.

Is that ounces by weight, or fluid ounces?

A US fluid ounce is a volume and there are eight of them to the cup, so that same cup is 8 fl oz at the same time. The two readings coincide only for an ingredient that happens to weigh eight ounces to the cup.
