Is the canon ef 100mm f 2 usm worth it?

Yes, if you shoot full frame and want portraits with a soft, blurred background. At f/2 it separates your subject well, and on full frame it frames as a true 100mm. It's not stabilised, so keep your shutter speed up in dim light.

For full frame, the Canon EOS 5D Mark IV gives you room to grow, and the Canon EOS 6D Mark II is a lighter option. On an APS-C body like the Canon EOS 80D, the lens acts like a 160mm, which suits distant subjects more than portraits.

If you're not sure full frame is worth the cost, the Sensor sizes guide explains when it really matters.
