The draft changes with the change in displacement. This is why Kuznetsov, Liaoning, and Shandong have different displacements with the same hull.
making a ship’s draft as deep as practical is actually good design practice, because all else being equal, a deeper hull is hydrodynamicslly more efficient. However, practically how deep a hull can be is constrained by the depth of water where the ship must operate, and the dimensions of docking and other support facilities, and the fact that most warship needs some margin to accommodate weight growth through its life.

Consequently, if there no other rigid dimensional limits, such as the width of locks on the panama canal, when two large warships of broadly similar size are both designed from scratch, their initial drafts will tend to be constrained to be the about the same by the same set of considerations, the difference in their displacement would be menifested primarily differences in length, beam or block coefficient.

Chinese navy have no real constraints on beam on length that I am aware of. this suggest their large warships would all be designed like to have the same maximum draft practicable, while their differing displacements reflected in their differing length and beams.

That is correct. Kuznetsov, Liaoning and Shandong are build on the same design with some alternations between them using the margin to accommodate weight growth throught design life. 003 is the first new carrier design with an other length, width and may be draft and a new hull-shape.

Again only a very blurry image showing the latest progress on the Tpye 003 aircraft carrier's construction at the Jiangnan Shipyard in Shanghai. But at least it seems as if there is what appears to be an additional extension on the port side.

It looks like the overhang is being put on now, no doubt about that. But I think the ship is large enough that they need to do a lower row of modules first, later followed by an upper row for the flight deck.

The overhang on 002 is thin enough (only 3 decks or so?) that it only needed one layer of modules. But as 003 has 10 decks like a USN carrier, it's probable that the overhang is 5 decks tall, so it makes sense to have separate modules for the lower overhang and upper overhang.
