For context I am located in Florida and I keep my AC at 76 and never keep the doors opened, but the blinds are up because we have house plants. People say to turn AC to 80 in the day to make it cheaper since my electricity ends up being 200$+ on average. Wouldn’t it cost more for it to constantly being going up to 80 and back to 76!?????

No.
Your AC is battling the heat gain into your apartment. This effort is proportional to the heat difference between inside and outside.
If you let it warm up while you’re not there the rate of heat gain rate is slower while it’s warmer, so the AC is working less.
When you come home and turn it back to 76 you just have to cool the air down once, this takes a lot less energy than keeping it cool the entire time.
Or in another way:
Say your apartment takes 30 minutes to warm up to 80 after your turn the thermostat up, then it stays there the next 9 hours until you come home. You only have to undo the first 30 mins, not the full 9 hours and 30 mins.
