I used latex ceiling paint in my room. It's not antifungal, nor does it clean as easy as a semi-gloss, but ceiling paint is formulated for maximum reflectivity of diffuse white light. Zinsser Bullseye 1-2-3 Acrylic Primer is a good bright fast drying undercoat.
Gloss paint or reflective foil doesn't diffuse the light. It appears to be more reflective because of the glare.
