It would seem that for pre-cooling, a high fan speed would be better. The
hot air in the far reaches of the room would reach the return intake
sooner. Then slow it down after it's comfy. Not disagreeing, just
wondering.

It would make the room feel cooler all over faster for the reason you state.
Depends on how long you pre-cool and how hot it is starting out. The system
can only take away so much heat at a time so that is the overall answer for
total comfort.
