Hello kronie19, and welcome to the friendly Camera Labs forum!
Do you want to show the whole room or "just" details/sections?
For the whole room a extra wide-angle lens/zoom is a must
Any lighting problem can be solved with a tripod
Btw. I moved your post to the "Architecture and urban landscape photography" section as your Q is independent from the camera manufacturer.
