I would probably recommend Provia for the better color neutrality, great fine grained film with a more natural color rendition, plus the extra stop of being iso 100 can help in a lot of different situation. Velvia is the main film that I shoot, but have done many projects of the nature your going to do and found that for guide books and other stuff the provia is a better film.

Most of all have fun.
