I've checked both my Boxsters gauge reading against the climate control (hidden menu) reading.
Both cars will run at 92-95c (197-203F) running around town, while the gauge barely budges past the 180 mark. I don't know what your coolant is running at if the gauge is indicating 210 or so.

I find it very hard to believe your cars run at those temps in traffic and Florida heat.
Can remember the trigger point for low speed fans, but it can't be much above 95 and I very much doubt the low speed fans will keep your temps below 95. The engine in generating a lot of heat, the ambient temps are hot and your natural airflow is nil.
Unless, of course, by around town you mean cruising at 30 to 40mph. But even then I would expect to see temps a bit hotter than you are reporting. In stop-start traffic, I would have thought 95 and below was very unlikely.
My 2.5 runs a lot hotter than that around town, and that's will brand new rads, new water pump, new stat. To be honest, fitting those things didn't make much difference, my cooling system was working just fine beforehand.
It's worth noting that the high speed fans on a 2.5 at set to trigger at 108 degrees C, which gives you an idea of what is considered hot by the engine management system.
Surely you trigger your high speed fans in Florida heat in stop-start traffic?!
