Johnathan BTW about the mixed white balance. You could just do it the way most movies do. What I have come to do and what most “cinematic” productions do is just use a white balance of 5500 K. As a photographer and videographer I use this all the time and it looks good and natural to the eye.
Here is an example of extreme mixed lighting all shot at 5500K for a church. Notice how the drone and slow motion footage don’t throw you off even though its not properly white balanced at all.

(Edit: To elabrorate on this, the way it was explained to me was "You can mess around on trying to get it perfect in every frame and it will NEVER look right, or you can use daylight WB that your eyes are most used to and let them do the correction.)
