We don't talk about Pun-Pun
Charisma would make sense for some classes like the Warlock, where you might have to bargain with your Patron for magic. Though by that standard, Clerics should be Charisma-based, lol.
With Bards, their magic is tied into the way they express themselves, by word or music- the skills tied to that are usually associated with Charisma, so it powers their magic by default, even if other factors, like the ability to compose and memorize songs (Int), manual dexterity to play an instrument (Dex), or the ability to sustain a note or use circular breathing (Con) would be important as well.
Now Sorcerers...I couldn't tell you why Charisma is the ability score they landed on. Most explanations are half-hearted at best. My personal headcanon is that, after deciding that dragons would use Charisma as their casting stat, as not all dragon types are particularly intelligent or wise, but they tend to be charismatic (at the very least, because they are imposing and frightening), and making Charisma the "innate magic" ability, it just made sense for Sorcerers to follow suit.
