There are no films that are "fashion film," "landscape film," or "people film," unless you simply lack all vision and cannot make your own decisions about your pictures. You have to know what you want from each of those situations, because they are highly variable, and what photographers want in them is even more variable. My advice is to not get stuck into ruts of what film is for what purpose. Learn how different films act, and use them when called for, in any situation.
If you want to achieve pastel colors, the best thing you can do is to shoot pastel colors in the first place. If you simply mean that you want to use colors that are all pretty high in tone, then lighting will make more difference than your film. If you mean that you want low contrast, then I would not use Kodak VC, Ektar, or Fuji C. I would use Fuji S or Kodak NC based on what you have said. I would opt for the Kodak for standard portraiture, and the Fuji for products. If I wanted WYSIWYG, I'd use Fuji Reala, hands down, if limited to C-41 films. If I wanted WYSIWYG in a transparency film, the number one choice for me would be Fuji T64 (needs tungsten lighting), followed by Kodak EPN, then Provia, then EPP, then E100G.
The only one of the two color neg. films I suggested that is still made is the Kodak 160NC, though finding the Fuji in stock and fresh from a retailer should not be difficult. The only ones of the positive films that are still made are Provia and E100G. T64 should be available at may retailers, but EPN and EPP will have to be tracked down through E-Bay or some other source.
However, as I said, the color design of the shot and the lighting will have the largest effects.
