The second look like they are designed for stairwells so I'd be a bit wary about using them up higher as the light might be a bit "spotlight" and not diffuse enough. I think both styles work with your house design

It looks like an old coach light, my grandmother had almost identical ones on her front porch, they have upped the anti on the design, it may be hard to find, maybe try antique stores.

You would have to look at the size of the space and purchase a light that is proportional to the facade. My suggestion would be two lights positioned either side of the front door.

The idea of wall lights is to shine light equally on both sides of face while doing makeup.
