I've had a lot of cognitive dissonance surrounding the way int, wis, and cha are conceptually handled in d&d over the years, and at this point I honestly think a lot of it can be attributed to the fact that clerics use Wisdom for their spellcasting mechanic, when that frankly attaches baggage to the score that is inappropriate. The entire concepts of willpower and devotion should revolve around Charisma, not Wisdom. Charisma is what enables a priest to emulate and draw power from the deities they serve. Wisdom is fundamentally about emotional maturity and the application of reason, which has little to do with piety and is the antithesis of dogma. Organized religion (regardless of its truth or lack of) is largely based on authority, and this is even more true in most D&D religions.
So, I guess what I'm saying is - I think Charisma makes about 600% more sense as a spellcasting stat for Clerics than wisdom. Wisdom should, at best, be supplemental for most spellcasters, with the possible exception of intuition or nature based magic.
Thoughts?
I agree with you entirely. Charisma makes a lot of sense for both Clerics and Warlocks. In fact, in many ways Warlocks are essentially arcane versions of Clerics. Both are building a rapport with, and/or serving a powerful being far beyond themselves, and trying to convince said being to further the ends of the Cleric or Warlock, often by either smooth-talking that they are trying to, or genuinely trying to, further the powerful being's goals with their actions.
Sorcerers, on the other hand, never made sense to run off Charisma, in my opinion. Sorcerers, and probably Psychics (Mystics, whatever

) should run off of Wisdom.
The way I've always seen the stats in D&D is as follows:
Intelligence is the raw ability to compute, to reason, to take all of the information one assimilates from the world and organize it, make sense of the patterns.
Wisdom is the ability to take the plethora of information one gains, and to most efficiently utilize it, playing to the strengths one possesses. This not only covers perceptiveness and intuition, but willpower; willpower is using your own mental resources as efficiently as possible, bringing the maximum offensive and defensive use of each thought in as small an amount of time as possible. A wise person knows when and how to use their intelligence and their charisma, and more importantly when not to. Both of these, to me, speak to raw strength of will.
Charisma is the ability to take your strengths, and best influence others with them. Some charismatic people know how to use their looks. Others their words. Others, their lack of words; the dark, quiet, mysterious stranger who immediately grabs everyone's rapt attention the rare times they speak is very adept at using their charisma! Regardless, Charisma is directly influencing others with your actions in a manner that achieves what you wish to achieve.
To me, the inward power and strength of will that sorcerers, born with their power and having to learn to hone these potent innate abilities through strength of will and intuitive efficiency reeks of Wisdom, not Charisma.
I can see the argument for psionic characters using intellect, meticulously honing their skills. I would likely have a split, where the learned psionic characters use Intelligence, while the wild talents, those born with immense psionic potential who learn how to use it on their own, use Wisdom instead.
But yes, I 100% agree with you. Charisma makes a whole helluva lot more sense for Clerics than Wisdom.
