This was a sticking point for me as well.

Honestly I don't get the limitation. I'm assuming there were trade-offs involved, but it seems like an odd feature to sacrifice.

Pro motion displays have only ever been available on devices with the “pro” moniker, there was never a chance of the MacBook Air getting it.

Are 120 Hz 4k or 5k external displays common?

144hz 4K is common yes. 5k upwards there is nothing above 60hz.

It's not much, but there's a LG 5k2k at 72 Hz.
