I bit just right into a strawberry the other day, and noticed a gas exchange between the hollow part and the surrounding air, meaning there was a pressure difference. That got me wondering, what is the gas inside a strawberry? How does it get there? Is it just air from wherever the berry was grown, or is it mostly CO2 because it's a plant?

it is a large intercellular cavity. you are right that the CO2 content is higher than in ambient air. however, there is exchange of gassess accross the cells so it is not airtight, you know. temperature and state of water saturation of the plant (turgor) affects air pressure changes.
in most plant tissues there are plenty of very small intercellular cavities - between all the cells- the tissue is like a heap of balloons, actually. it is to enable exchange of gasses as much as possible
(one of wild strawberry species, the Fragaria viridis has markedly tough cells around the stalk, so when you pluck the strawberry, it makes a distinct noise (like smacking )
