My upstairs used to run about ten degrees hotter until I installed a booster fan in the duct to pull cool basement air up there. I know they’re generally ill-advised for most scenarios, but it works incredibly well for me in summer since it would have been a very expensive proposition to upsize the vent, install a return, or put in a mini-split.
Usually around 76/77.
