I sometimes use fuji pros S at 125 for landscapes, as mentioned above by Walter, and I use pro h for people, rating at 320 or 400, depending.
Let me throw another thought into the mix and suggest considering slide film like astia or velvia. If you're going to be scanning then [properly exposed] slide film will give you more bang for your buck, in my opinion. At least for landscapes. In my opinion, colour neg film doesn't scan so well, it looks better when printed directly, whereas with slide you can get a lot of very clean information out before hitting the grain.
