I recommend going to voltlighting.com I bought a bunch of their fixtures and have been thrilled with them.
Down fixtures can bathe a wall, but up fixtures can add some interesting effects. There are up/down lights that do some nice things as well. The gooseneck fixtures look good as an accent piece not a real good lighting solution in my opinion. The quality of low voltage LED's today allow you to have way more light for way less operating costs with a ton more options than more traditional fixtures.
Last thing I will add is I believe lighting looks best when you do not see the fixture, especially when used to accent the structure, there are so many options to hide the lights in the eves today. Specific point lighting allows you never to feel like the light is in your face when planned properly.
Good luck in your quest.
