The classification is also quite blurry in the books, but bruxas and katakans are technically higher vampires. In Baptism of Fire, alpors, katakans, moolas (or mula), bruxas and nosferats (nekurats in games) are all higher vampires and the only forms of lesser vampires are fleders and ekimmas. Geralt also remarks that this is every known class of vampire, excluding imaginary ones. The same would apply to the Queen of the Night and the ancient katakan - they are both higher vampires.

It seems to me that regarding Oriana, those events in the trailer likely did happen. As you said it came out before the expansion, but it seems like CDPR worked Geralt's last dialogue with her to open up the possibility of the events of that trailer happening. Oriana was a higher vampire, but she was also confirmed (see notes) to be a bruxa, which is a class of higher vampire. The two are not mutally exclusive.
