If in a coordinated turn, the horizontal lift vector is equal to the Centrifugal force. Then...
situation from ground, there is no centrifugal force (because this fictitious/inertial force appears as a consequence of applying laws of motion in rotating reference system) and horizontal component of lift … They are missing part of aerodynamic force generated by side-wise motion through air, which is definition of slip and skid (you can call it drag or airframe-lift). …

What is the "Centre of Pressure"?
Center of pressure is not a point "where the lift is most concentrated". … Center of pressure has very little relation to how is lift distributed along the wing (you can have exactly same centre of pressure for infinite number of different distributions of lift). …

Are wings any more efficient at creating lift, versus orienting the engine's thrust downwards?
Higher mass flow rate over the wing (longer wings, higher airspeed) makes it possible to keep the same lift with lower deflection ($\alpha$), thus less drag due to the generated lift. … But it should be still worth of it as the gain provided by lift is greater.
A simplified example: We have an engine capable of producing enough thrust to lift aircraft vertically. …
