When I know it’s going to be a warm day (Minnesota is still getting snow currently) I’ll kick the AC on when the ambient temp is right about the temp I want it to stay at. At that point it’s more so maintaining the temp, more than working hard to bring the overall temp down. I’ll kick it off at night when it starts dipping into the 60s/50s again.
Once it’s consistently warm however, I’ll just let it run until the cold comes back

I’ve never approached it based on the outdoor temperature. I set the thermostat for whatever indoor temp I want to maintain.
There’s no rule that will work for everyone, because all houses are different. Some have more insulation and double pane windows. If you have a less weatherproof house, you’ll never make it to the highest temperature of the day, because the indoor temp will be several degrees higher. 90 degrees outdoors could equal over 100 degrees indoors.
When I was still working, we’d set it to 83 degrees while we were away from home, and then lower it when we returned. If we had left it turned off altogether, it would have been impossible to cool it down when we returned.

I think more important than when you turn on the AC is remembering to close your blinds/curtains around 10 AM if you can to reduce solar heating, and then opening windows at night if the outside temp dips lower than 70. That can make a huge difference on really hot days. The less work the AC has to do, the better it works! Most ACs have an energy saver mode where they will come on when the indoor temp reaches a set number. I would set it at 72-75 (depending on preference) and let it decide when to turn on and off.
