If you're going to run fiber cables, run two or three. At least two.
You don't want to do that twice if you don't have to. And if you need to troubleshoot your layer 1 at some point in the future, it's a lot less frustrating to have a good spare versus having to run more later just for testing.
I would go with 2 in aggregate (if you have the ports) + 1 spare.
But yes, fiber would definitely be a better option if you have enough clearance to run it without kinking it. Might even be cheaper depending on the cost of copper these days. The real cost is usually in the SFP+ modules.
Definitely do some research on the switches that you have before you buy the modules and cabling. Certain modules can be finicky with certain switches.
