Jellybeans are the cheap and ultra-common parts that one uses for electronics. Like 10k resistors, indicator LEDs, or 0.1uF caps
Useful for boards with limited surface area. Not as small as 0402, but can still be hand-soldered and they use standard reel holders (0402 reel holders are more expensive). These may be harder to hand-solder than 0805, though, so if you are also using the components for hand-soldering and only want to stock one-size, 0805 may be a more appropriate 'general-purpose' choice.

We arbitrarily (well, not completely arbitrarily, but kinda close) decided to go with 0805 for our jellybeans. Not as big as 1206, but not as hard to solder as 0603!
