What is the correct import settings for Final Cut Pro v7.0.3 to import iPhones 6 and Go Pro 4 videos Final Cut

I have a project to editing massive amount of video clips shot by iPhone 6Plus and Go Pro 4, what is the best setting for me to edit these clips in the Final Cut Pro 7.0.3 ???

Currently, the caputred video clips are at following settings:

for those Go Pro 4 videos:
Format: MP4
Dimensions: 1920x1080
Codecs: H.264, AAC

Color profile: HD (1-1-1)
Audio Channels: 2

for those iPhone 6Plus videos:

Format: MOVDimmensions: 1920x1080
Codecs: H.264, AAC
Color profile: HD (1-1-1)
Audio Channel: 1

So waht is the best setting for me in the final cut pro's Easy Setup and Audio/Video Settings in order to save the rendering time and the disc space？

Thanks in advance.
