Reflections with a print that large could definitely be a problem. Most galleries do know how to handle lighting to minimize it, however. Most of the prints I see in exhibitions are either on glossy or semi-glossy paper (either true silver halide or inkjet printed). Glossy and to a lesser extent, semi-glossy will give you deeper blacks and better contrast. With the greater contrast will also some a slight increase in apparent sharpness.
