Use the ACES or FilmLight scene template. Put the footage into the timeline and use 'Automatic' or 'From Metadata' tagging for the Input Colour Space. Then on the render page select the desired log output colour space.

There is nothing stopping you from rendering a log colour space into exr files. But a 10bit dpx will give you more image quality than exr in this case. Best would be rendering to 16bit dpx (for log colour spaces).

When you render a log colour space into exr, you might see banding in the image.

Yes, if there is enough noise in the images the banding is masked by the noise.
