Pull-down, judder, film modes? Do they impact monitors?

I have a TV that does "True 48Hz" with "2:2 pull-down" and on white backgrounds I can see a bit of flicker in that mode. It appears that refresh rate MODES aren't necessarily refresh RATES..? That same TV allows turning that 48Hz mode on and off, so I have options:
1. 48Hz mode off (in TV settings) with 23/24Hz refresh rate selected in NVidia CP = no flickering, but worse motion (judder)
2. 48Hz mode on (in TV settings) with 23/24Hz refresh rate selected in NVidia CP = slight flickering, but smoother motion (no judder)
Newer TV's have similar film modes without flickering due to 3:3 (72hz) and 4:4 (96hz) pull-down. So... without those film modes, 23/24Hz refresh rate selected in NVidia CP is not actually true 23/24Hz..? It's still 60Hz... or at least still in 60Hz MODE..? CONFUSING!
Does any of that affect monitors? G-Sync? Free-Sync? Are 144Hz, 165Hz, and 240Hz refresh rates actually refresh rate modes or refresh rates within 60Hz mode and 3:2 pull-down?
