Put down a very large driveway last year so I can only give you my experience. We are in the north too, so enviro is different. My driveway is 1,000 ft long. About 12,000 sq ft total.
Ours is 5” thick on 5” base. In some spots the old gravel driveway that was 100 yes old was so compact and hard they couldn’t excavate, so the put down a few inches of base and poured on that. We did not use fiber mesh. It’s cheaper and easier, but doesn’t hold up well outdoors is what we were told. We have full metal mesh laid through the whole thing.
We have hand-tooled joints about every 8 feet mostly because it’s so large and risk of movement with weather.
It’s hand broom finished and sealed.
It’s overkill, but I expect it’ll be around forever. I’m not sure you need all that in the south.
