Anyway, since cloud and ground are oppositely charged (otherwise you
would not get discharges in the form of C-G lightning),

and C-C lightning shows charge varies within and between clouds

Before C-C lightning the voltage is different within and between clouds.
After lightning charge varies and the voltages become equal (for a moment)

The ground and clouds are both negatively charged (exces of electrons).
Different is the voltage.

So where are the positive charges?

We must distinguish the charges from the charged bodies. Droplets are
bodies. In electrostatics the positive meens defficiency of electrons and
negative the exces of electrons.in a body. Droplets when hang in the air
have exces of electrons. If they loss them have to fall down (Millican).

All what I am talking about was explained in XIX century. In that time
Armstrong made the vapour generator (of high voltage) and Kelvin the drop
generator. The all was described by J. Frenkel in words: ".. Clouds are
electrogravitational generators in in continual run. In place of the
friction and the induction (as it take place in normal generators) are the
condensation and thedroplets grow."
But the most important is to remember that the surface of the Earth has
ALWAYS excess of electrons. They are ewerywhere and in sunny days migrate
up. It is obvious that they must come back.
