If you're taking I-75 through Ohio just split off on I-71 southwesterly from the Cincinnati area toward Louisville, KY. Then take I-65 south to Nashville where you can take I-24 back toward Atlanta and I-75.
Another option, the route we take, is to follow I-65 south from Nashville to Montgomery, AL and then US231 down to I-10. Depending upon where you're heading in Florida you can head further east to I-10 or take US19 south along the Gulf Coast of Florida. When taking US19 you can always hook back up with I-75 by catching US98 through Brooksville, FL. It's all 4-lane (US231 and US19), but US98 is 2-lane without much traffic. This is a pretty flat route to Florida.
I like this route south from Nashville. I also avoid 98 unless I am dropping down from I10 to a specific location. 19 along the west coast is a very pleasant drive. Few trucks and light traffic.
