It seems a bit, that the u,v,w-driven part of what I call "centrifugal force" is absorbed into the Coriolis force and when we speak about centrifugal force only the static part of it (u=v=0) is regarded. However, when this is the case, there is still one missing thing: when u=v=w=0 we have a point at rest in earth's reference frame.

This force, which becomes apparent when referred to a corotating reference frame, is the centrifugal force (fugo – I flee, like a fugitive). It would need a good lawyer to argue that the invisible gravitational force towards Earth is a real force, while the equally invisible force acting away from Earth is imaginary.

Centrifugal Force at the Earth's Surface | Justin A. Parr

Centrifugal force is the unbalanced reaction of inertia to centripetal force. So centripetal force constantly "pulls" us toward the Earth as we orbit, while "centrifugal" force is the inertial tendency of mass (our bodies) to continue moving in a straight line (e.g. flung in to space).

The centrifugal force may be fake, but from Observer B's perspective we need this fictitious force because it's not immediately obvious that they're in a non-inertial reference frame; from their perspective, it looks like there's a centrifugal force acting on the satellite that keeps it from crashing into the Earth.

How to explain the Earth's Equatorial bulge without centrifugal force?

The so-called centrifugal force is indeed a fictitious non-existing force in the inertial frame. But the centrifugal effect is very real. That effect is causing the bulging. The counter-intuitive thing is just that it is not a centrifugal force which is causing the centrifugal effect. Rather, the cause is inertia. Think of your stone-in-a ...
