There are very survivable fiber cables designed for stage and A/V setups for instance, and even "real" military grade ones. But the common thin LZSH stuff is surprisingly resilient in my experience, so long as it didn't kink the OP would probably have been fine with a "standard" cable. In any case I would always try to place fiber in a place where it can be re-pulled.. conduit, tray, or a plenum.

I bought a big spool of 6 strand Corning stuff a long time ago for various projects, the cost and diameter don't increase much to add some protection lines even if you never imagine using them they can save you a re-pull if you bugger something up in construction.

The contractors were probably dubious of that resiliency given their lack of experience. I recently ran fibre in my house and have to say I was pleasantly surprised that fiber patch cables (unarmored) can survive a good pull through a duct.

You can kink the shit out of fibre and it’s fine. Like, I’ve accidentally managed ~15mm diameter loops while pulling and then proceeded to yank on them. The Kevlar takes the brunt. Only time I broke a fibre was when it was me and two other guys pulling on it as hard as possible - and instead of moving it went “ping”.
