It was hard to read, at least in the normal font size on my laptop, but the veneer mentioned is 1/8", not 1/2".
Well ⅛ is 1/2 the size of 1/8.
It's also way the heck up the ASCII so as to be practically unusable for normal thread posting. Why not also code the {3/4} ?
But I digress ...

My veneer will be 7" wide. The table is 72" long. I'm thinking of clamping over a full size plywood piece and 3 slightly convex cauls above that. i.e. 3 clamps each end giving somewhat even pressure.
I agree with Drstrip's advice ... attempting to do this in strips will not allow for tight seams.
Typically in veneering you'll cut/plane/sand the edges and then attach the strips together with "veneer tape" prior to glue-ing to the substrate.
I'm unclear how you're using the clamping cauls ... if the intent is to run then length-wise I would reconsider this approach as I do not believe you will be able to properly apply pressure the entire length of the piece. If they are run width-wise then you don't have enough.
I would suggest a sandwich ... solid surface such as plywood, a sheet of parchment / wax paper, veneer, glue, substrate, glue, veneer, a sheet of parchment/wax paper, topped with solid surface such as plywood. Then run clamping cauls every foot or so across the width of the top. I might even place cinder blocks (or any heavy object) in between the cauls or in places of suspect clamping pressure.
I would also suggest using a glue with a long open time to allow for fitment and clamp up.
Unibond 800 is one I've heard often, as well as a Plastic Resin Glue.
Here's a couple of video's explaining the hammer veneer process:
