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.

Question: Standard gravity for Earth is 9.80665 m/s2 and 32.1737 ft/s (based on 1m=3.2808 ft). These values take into account the centrifugal acceleration due to earth's rotation, which acts in the opposite direction of gravity due to Earth's mass. The Earth's diameter is 7,926 miles..

Centrifugal Force
The Earth's form: Another illustration of the influence of centrifugal force is the form of the Earth. Because of the planet's rotation, the Earth is flattened at the poles and bulged at the equator. The equatorial region bulges outward as a result of the centrifugal force created by the Earth's rotation.

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).

So by definition, there is no centrifugal force that can be measured. If the Earth's centre is to be considered as a reference frame then it is non-inertial because it is being pulled on by the moon, and so to make it quasi-inertial, a fictitious inertial force (since the word centrifugal implies rotation, which is not happening here) is ...

CC | Centrifugal force explained
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.

Centrifugal Force
Centrifugal force is the apparent outward force on a mass when it is rotated. Since Earth rotates around a fixed axis, the direction of centrifugal force is always outward away from the axis, opposite to the direction of gravity at the equator; at Earth's poles it is zero. (Centripetal force is the necessary inward force that keeps the mass from moving in a straight line; it is the same …

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.
