Another reason why F, F# and G may be popular keys to use in production is because how the bass and sub bass sounds. With the key being in F you can have a deep sub bass that still sounds nice because of the frequency the lowest F note falls in. While with other keys the lowest sub bass note is either way too rumbly or too high to even be in sub for example the key of C or B I find is hard to make a good sounding bass because one octave and it sounds too high, while the lower octave sounds too deep or flabby.
