Difference between capacitors of same value but different sizes
I would like to know why some capacitors have the same value (capacitance) but their sizes are different? What is different between those capacitors? For a given (fixed) set of constraints: Manufacturer, Manufacturing technology, Dielectric type, Target application, i.e.: decoupling, general purpose, high-frequency or power line filtering,

Why does the area of the plates affect the capacitance?
If you have a larger plate, the charge can distribute over a larger area, there is less "pileup" and therefore a smaller "pushback force". This is why, with larger plates, you get a bigger charge into your capacitor with the same voltage.

A capacitor with a large capacitance is able to store more charge per voltage difference. Capacitance is proportional to the area of the capacitor plate, the larger the area the more charges can spread out without repelling each other. This is analogous to the area of the cylinder, the larger the area the more volume can be stored in the cylinder.
