Keep the higher refresh rate. Ditch the smoothing. Motion smoothing makes everything look weirdly artificial.

This. Although it makes sports and news look better... usually. Although if the source material is broadcast in 30/60 fps, and the 120hz refresh rate is just showing the same frame 4 or 2 times, there's really no net difference, although the image might look a bit more "solid". It's when it decides to use the extra frame to simulate it's own picture that's "in between" each time actually creating a net percieved gain in visual information and "smoothness" it gets really, really weird, depending on the programming you're watching.
I'd guess if you just "toughed it out" for a few weeks, or maybe a few months depending on your viewing level, it would look "normal" again.
It's actually weirder to me that our brains have been wired to perceive 24-30fps with "expensive" and "drama/fiction", and higher video-like fps's as being "live", or "local", or "inexpensive production quality".
Although IMAX which I believe has a higher fps projection rate somehow doesn't suffer this. So it's not just that.
