I was comparing color films, but sure, speciality black and white films can approach the resolution of current high resolution color cameras, with the drawback that the lack of stabilization will make these resolutions only achievable with a tripod and of course only for static subjects, in which case pixel shift is probably a better option.

And yes, you can use medium or large format film, but that comes with very serious drawbacks, and for low ISO film is literally impossible without a tripod, in which case you might be better served with sensor shift instead.
