94 Firehawk cooling help

Hello I have a 94 Firehawk LT1 and I live in the mountains of North Carolina.
On a typical drive the car runs 180 temps then in traffic stops it runs right to 200-215.
When I get the car back onto road speeds it cools back down to 180, this happens every time I go out, normal outside temps are 80ish. I'm getting afraid to take her into traffic.

I see all the banter about different fans going on at different temps and added switches you can add to help them kick on.
I'm not a mechanical wiz, but I just finished a total body and interior restoration on this car and its beautiful now.
My mechanic is hard to get a hold of so maybe someone could suggest a fix or a schematic or diagram I could look at to figure this out.
I know alum heads are subject to gasket problems due to excessive heat.

Its hard for me(us) to help you with a problem, when it doesn't seem like there is a problem. The temp is always going to go up in traffic since there is not as much air flowing, then temps will go down when there is more air flowing. My car acts the same way. 210 is not overheating, and is in the normal range. At 210 the low speed fans are still ~10 from turning on.

My car does the exact same thing and it bugs me too. I ordered a fan switch from SLP it look relatively easy to install.

The fans are programmed to come in at 235 degrees for the primary and 240 for the secondary. I wired a switch into the green wire on the primary fan relay. This green wire is the ground signal the PCM gives the relay to activate the fan. I wired the switch to the relay to supply the ground when I want the fans to come on. This not only keeps your electrical system from experiencing any overload or sending power to something that shouldn't get powered or back fed but only incorporating one of the fans will allow the secondary fan to still come on at 245 degrees in case the switch were to fail. Just be sure to dead head the other end of the green wire that goes back to the PCM. the switch I used was just an after market fog light switch.
