I put the cheddar in the kitchen cabinet

I had a similar issue just recently, where my apartment lost power for twelve hours before being restored. With the doors closed for the entire time, the temperature raised only a few degrees, even the milk had no difference in taste, with it only being cool as opposed to cold like usual. Like yourself, it was also at the peak of summer.

Fridges are usually pretty well insulated (as they'd have to be, or else the motors would never stop running to keep cool during the peak of summer), so outside of the eggs, if it was never opened, I wouldn't be too concerned. I only put a caveat on eggs because as someone that cant' stand eggs, I never buy them, and hence have no knowledge of how susceptible to temperature changes they are.

EDIT: Personal opinion. Do not take this as a green light to start making bacon omelettes with a big heaping glass of milk today.

Same answer as always: you don't want to eat any perishable food or food for which any part has spent more than about 4 hours cumulative over its lifetime in the danger zone (40 - 140 F, 4 - 60 C).

Do you know how the pizza place treated the calzones before you even received it? It may have been sitting on a shelf at room temperature for an hour or two at the store before you ordered it, in addition to the transport time when you took it home, and all the times as you heated and cooled it when it was in the zone.

In general to reduce the quality degradation, and the amount of time food ends up moving through the danger zone, you normally only want to heat up the portion of food you intend to eat, and leave the rest refrigerated.
