As for how Pakistani friends describe JF-17B3 and J-10CE, this is your point of view.
In the formal and relatively rigorous description of the Chinese official agency, the J-10C is a 4th-Gen fighter with avionics level close to the 4.5th-Gen fighter.
Its meaning is very clear. In the official and rigorous title, it is not what we think of as a 4.5th-Gen fighter. Chinese people generally believe that the J-10C is a 4.5th-Gen fighter, but it is the worst fighter of all our 4.5th-Gen fighters.

This is an internal matter of Pakistan and we will never interfere. We just provide an option to Pakistan, and the decision of how to choose is in Pakistan's hands.
The Chinese government will never interfere in its internal affairs. This is our bottom line!
========================
Regarding whether the J-10C production line can be exported. This is just my speculation, please be cautious!
