Left side flange position is dependent on over lock nut dimension. Ideally, you make the frame wide enough so that you can have no dish. With wide freewheels, that is the limiter.

I'd start first by designing so that there is a very close proximity between the cogs and the flange on the right side. Some hubs leave too much space there and that aggravates the dish problem and is hard to make up for with left flange position. Boy, I hope that's clear. It makes sense to me, but just reading someone else's (my) words may be harder to understand.
