I'm thinking fixed gantry but I know with a mobile gantry I will get more cutting surface.

Rack and pinon would be easier on the wallet from what I've read. Is this correct?

Rack and pinion would have even worse precision than roton Lead/ballscrews and also have more backlash. You're best bet would to be ask this question in the DIY Wood Router CNC forum.
