CAC-1170, Active Mini DisplayPort (1.2, aka Thunderbolt 2) to HDMI 2.0 Adapter with Mac Pro 2013 (Family 6,1), hoping to achieve a 60Hz refresh rate signal to compliment the 4K HDR TV

Mini DisplayPort 1.2 is not Thunderbolt 2. The connector is the same but the technology is different. Keep that in mind. It’s like saying USB-C is the same as Thunderbolt 3 ;).

Based on the above articles I would say yes CAC-1170 should work for your setup.
