ELI5: Sometimes raindrops are misty, sometimes they’re large. Why? What dictates the nature of raindrops?

Raindrops tend to be bigger the lower they fall from and the higher the air pressure.

More rain, less wind and lower clouds tend to result in bigger drops.

Temperature also has an effect, because the colder water is the greater the surface tension (which makes the waterdrop more resistant to splitting up).
