Here is a chart that explains the differences in the cable types
I'm running fiber from my house to the detached shop. I need two networks, regular network and security cameras. I'm putting in 2" conduit since I did not want to direct bury and wanted room for "the future". I need a 250' cable, 180' will be underground. Talking with the vendor, I'm going to use Indoor/Outdoor, not direct bury since it will be in conduit and deep enough to not suffer through hard freezes in my area. That's the detail around my install.
I decided to use 6 strand 50/125 OM3. That gives me the 4 strands that I need for two networks and a spare pair. At 250' I can support up to 10 Gb and higher than that if I pull more strands through that giant conduit later. The price difference between a 62.5 and a 50 OM3 indoor/outdoor cable was about $35. The cable price is $342.50, which includes a preinstalled pull sock.
In contrast to that, when I ran fiber from my basement to my attached garage, I bought a 100' 50/125 "patch" cable off of ebay for $20 and used that.
Hopefully my rambling isn't confusing, I thought it might help as my situation is somewhat similar to yours.
