Canopy extraction

[Baxdream]

We are having the attached design in our new kitchen.
What extractor do I need? It's very confusing! I'm currently looking at the Miele 2578

I've got a similar set up, my builder recommended one that was the right spec for building regs, and the right size for the space, I didn't really give it much thought because you can't really see it, I just wanted to make sure it had lights in over my oven

Thank you. We've got different trades doing each part so haven't asked really.
