Optimal Settings For Doing a Chroma Key with the Pocket 4K

As the title suggests, I have a Blackmagic Pocket 4k and I want to do some chroma key/green screen stuff for fun. I know I want to export in 24fps at 4K DCI (trying to future proof myself). I am also unsure if there is value in shooting in 60fps as well as possibly increasing the shutter angle to 45 degrees? I plan on shooting in Q0 BRAW and at 25mm-35mm f/4-f5.6, but should I consider doing something other than being at 180 degrees shutter angle and at 24fps?
