I'll chime in since nobody else is. The short answer is...it is entirely subjective. Plus you can do what ever you like (cheat) to get the look you're after. If you want it to look like images we are traditionally used to viewing then there are a couple hard and fast rules from the old film days.
When we used to shoot interiors on film the first rule is selecting your film size. This decision was based on the maximum reproduction size needed for the final image. We would shoot on the smallest film size we could because the smaller the film (now sensor) dimensions the greater the depth of field at a given fstop. Nowadays with digital sensors this is somewhat irrelevant. With CGI it is totally irrelevant.
Once the film(sensor) is established then that narrows down the choice of lenses. I'll speak in 35mm terms here but if you wish to go with 70mm then the lens focal length also needs to doubled (roughly). i.e to get a 24 mm lens on 35mm angle of view on a 70mm sensor you would need a 48mm lens (roughly). So with that being said, a small room interior would be shot with a 20mm to 24mm lens. Sometimes a 28mm if at all possible depending on the scene. But here we would pick the longest lens possible to reduce distortion. Ive photographed interiors fromr outside through doors or windows or at the very least scrunched into the corner of a room to use the longest lens possible.
I think it was Richard Avadon who famously said "Photography is 10% inspiration, and 90% moving furniture."
God I love CGI.
