Fomapan 100 is wonderful, as is the Acros 100 (and Delta 100 too, and throw in Kodak for good measure) - all the 100 speed B&W films are very good, I go by price and availability when I replenish my supply. There probably are differences between the films, but not significant for me to have developed a connoiseur aproach (yet)
At 120 size, the grain etc on a good 400 speed film (Tri-X etc) isn't as big an issue as in 135, so I've also used Tri-X and Tmax 400 for landscapes, with good results. Foma 400 I'd consider a special purpose film, as it tends to a vintage look.
Non-slide color: I tend to follow the same pattern, whatever 160 speed film is cheaply available when I replenish. Fuji 160S has been good for me, but if I pick nits Kodak 160NC gives even better results. These I use as general purpose films. 400H makes for a good higher speed portrait film, perhaps it is a bit unassertive for landscape work.
