The difference in pricing between high resolution full frame cameras and medium format cameras has shrunk considerably. When you look at the current sale price of Nikon, Sony and Fujifilm mirrorless and even DSLR cameras there is very little difference. However the only Medium Format camera in this price range is the 50R with the 50mm (40mm in 35mm equivalency). Size wise the 50R is larger than the other cameras with the exception of the D850. All of these cameras are fairly light and small enough to do street photography.
