There was a lecture on YouTube given by the retiring aerodynamicist at Boeing that seemed to boil down to 'we don't understand lift'.
The bit on top is Bernoulli and he bit underneath is Newton (3rd Law).
But when you resolve all these forces, there seems to be a bit left over (or under).
I had a look at Kermode 'Mechanics of Flight' , didn't get very far, then found his book 'Flight without Formulae' which helped a bit.
There's a principle called 'Lies to Children'. This is where we give simple, incomplete explanations to children to answer their questions, to the extent that the over-simplification could be called an untruth or a lie, because it misses out essential stuff.
This is certainly the case in our explanations of aerodynamics at the PPL stage and probably beyond that.
