Of your picks, I'd recommend the 17-40, it is equivalent to about a 24-70 on your crop body about.
Honestly there is not much else that could give you the range you want for a wide walk around lens.
I know it is important to think about what lenses will work for you in the future, but the thing is, that if you get a good ef-s lens that allows you to take better images, you won't be at a loss if you can't sell it for a good price.
Photography isn't about the lens or the camera, but the combo. Ef-s lenses are made to be better than ef lenses on crop bodies.
You should only upgrade to ff when you have the money to buy both the camera and the lens.
This is especially important for wide-mid zooms.
I strongly encourage you look at the canon ef-s lenses and some of the sigma's
