Salut, @nonophuran!
I am sorry: I do not really understand what you are after 
Words like “Natural”, and “Faithful” as used in the camera settings you
presented above are rather vague. (Not to talk about the “Faithful Standard” color,
which actually implies an “Unfaithful Standard”, as well.)
I wonder whether you mean something like “100% colour match”?
I.e. your object has a certain colour, let us call it XYZ. You take
a (RAW) photo of that object, and you would like to develop it so
that the object is presented on your monitor exactly as XYZ.
Is that a correct assumption?
(Then, perhaps, you would also like to distribute your image
and have it look exactly as XYZ on every monitor all over
France? And/or print the image in offset, litho, intaglio, screen,
&c &c &c — still looking like XYZ…?)
The closest I’ve come to something like that was: My first color management experiment
By all means not perfect, but pretty good for a non-professional set-up…
Amicalement,
