Welcome to The Forum. Your question does not have a solid answer, it depends on if the ceiling is an air return, and if the cable is penetrating a floor. I'll give you a hint... See 800. 154 a. Also, if this is not a test question, and a real-world install, you had better get this right... Inspectors don't usually pay too much attention to chapter 8 installations but if you use the wrong cable type I guarantee you you will be pulling it all out
When in doubt, use plenum rated. In fact, use plenum rated anyway. Wire is cheap, labor is expensive. Non-plenum is ~$75/1000 feet, plenum is ~$145/1000 feet.
95% of the time, CMR was all we needed for floor penetrations in hotels. between coax, Cat5e, and Cat6, I'd estimate I've installed close to a million feet this stuff, and if I bought all CMP versus CMR, would have spent about an extra $75,000 in unnecessarily on cable. I've never had to pull out anything I ran, we've had two jobs were the previous contractor screwed up and we took a pair of snips to all of his cable and re-ran the proper stuff.
back in 2008 the difference between CMR and CMP was more like $175 per box. CMP, in many brands has clearish insulation on the pairs of wires, and distinguishing the orange from the brown isn't always easy... Had a couple of them windup reversed or split between pins 1/2 and 7 and 8.
But yes point taken, you cannot go wrong with CMP is at the top of the cable hierarchy
I can understand if you're a high-volume shop that the delta can add up, but it has to be lost in the noise compared to your total labor costs.
I'm most familiar with fire alarm cable, and FPL to FPLP is about the same delta, but cable is usually the smallest material cost for any given fire alarm project.
