I’m not sure why Black and White film makes sense any more. When I want black and white, I can just choose “desaturate” in PhotoShop and it is done. Still, if you want to work with traditional processes (i.e., you don’t want to scan) and you want a negative that will last for hundreds of years, black & white is the way to go.
Actually, it’s more likely to be true of color film than B&W. But coming from someone who thinks desaturate in PS is the same as true B&W, who cares?
