The technician should use Plenum-rated Cat 6a.

Here's why:

1. The question specifies that the cable must be twisted pair. This rules out Plenum-rated multimode fiber, as fiber optic cables are not twisted pair.

2. The cable must be capable of Gigabit Ethernet speeds. This rules out Riser-rated Cat 5e, as Cat 5e cables can technically support Gigabit Ethernet, but not optimally over longer distances.

3. The cable is running above a dropped ceiling that is also used for ventilation. This means the cable must be plenum-rated, which is a rating that indicates the cable doesn't emit toxic smoke when it burns. This rules out Riser-rated RG-58.

4. Therefore, the only option that meets all these requirements is Plenum-rated Cat 6a. Cat 6a cables are twisted pair, can support Gigabit Ethernet speeds, and the plenum rating means they're safe to use in ventilation spaces.
