What kind of org shares cabs? Monster!

Your cab's environment should be pretty thermally stable. Your switches are probably venting to the hot isle through their front ports. Thermal expansion of glass and the sleeve is going to be negligible over a metre or so.

Kinking is a possible issue. The minimum radius these days is quite tight. However, if you don't leave enough space inside the doors to allow for the terminations it will go horribly wrong. If you don't allow a gap for cable management between all switches and top and bottom, it might go wrong.

I think that the person to whom you replied is speaking of outdoor installations, while you are speaking of controlled (maybe datacenter) installations. I have outdoor fiber running aerially between buildings on my property, in a region with massive seasonal temperature changes. Multiple local FTTH and Coaxial ISPs also run fiber on shared utility poles (the same ones that the electrical grid maintains) and when I look at the poles I see communications lines all in the same general area, often mere centimeters apart, if that.
