Skylight mobility when baking large interior

Need some expert lighting advice from any precomputed lighting wizards.
When creating lightmaps for a large interior scene (think stadium with some fog-atmospherics) what should you typically set the mobility of your Skylight to?
In my case I have it set to Capture Scene and using GPU Lightmass.
I’ve noticed that if I set it to Static before baking, if I switch it to Stationary or Movable afterwards the entire scene lighting changes somewhat.
Thanks!
