When I setup project and select 60fps it changes to 59.94 on export
Sony camera set to 60fps but upon exporting changes to 59.94 fps with sketchy audio.

What is the actual media? Open a clip in the QuickTime Player and see what it says in info window. If you want the project to be 60 you can make a custom project.
