A campus backbone design linking two buildings requires that you install a high-fiber-count cable very quickly, using the conduit system provided. Cost is not so much an issue as urgency is to meet a

Multiple sheathed cables require more pull operations and fill more conduit space, and field connectorization adds significant on-site termination time, conflicting with the urgency requirement.

Multiple cables still require multiple pulls and pigtail splicing in a splice enclosure, adding complexity and time compared to a single preconnectorized cable.

A single high-fiber-count cable is the right cable choice, but field connectorization introduces on-site termination labor and cure time that slows deployment.

Pigtail connectorization requires fusion splicing pigtails to the cable ends in a splice closure, which adds steps and time compared to factory-preconnectorized assemblies.

A single sheathed cable is faster to pull through an existing conduit than multiple cables and reduces the risk of conduit congestion or fill-ratio violations. Factory-preconnectorized assemblies eliminate all field termination and curing time, which is the most time-consuming part of fiber deployment. Together, these choices directly address the urgency requirement while leveraging the provided conduit infrastructure for a two-building campus backbone.
