I honestly don't care about the exact refresh rate numbers too much. Latency is the more important thing anyway.

I agree refresh rate is often talked about, I reckon assuming short viewfinder lag. While assumption that fast data pipeline is also there is not unreasonable, it is surely not given. A short delay of image in VF - or latency - is indeed more important.

On the other hand, fast sensor (and VF?) refresh (can) be directly linked to AF performance. Other topic.

Fast sensor refresh is directly linked to AF performance indeed.
On the other hand, EVF refresh rate is unrelated to AF performance.
AF works by reading pixels from the sensor. The EVF is just for the user, nothing else.
