For example jung says this about extraverted thinking:
"Thinking in general is fed on the one hand from subjective and in the last resort unconscious sources, and on the other hand from objective data transmitted by sense-perception. Extraverted thinking is conditioned in larger measure by the latter than by former. Judgment always presupposes a criterion; for the extraverted judgment, the criterion supplied by external conditions is the valid and determining one, no matter whether it be represented directly by an objective, perceptible fact or by an objective idea; for an objective idea is equally determined external data or borrowed from outside even when it is subjectively sanctioned."
(Psychological types page 342)
You dont seem to know about this subjective factor of extraverted functions, but claim that this subjective factor is some shadow function.
So even tho ENTJ uses Te only, not Ti, there is subjective factor to the extraverted thinking, the difference really is just that with extraverted thinking, only the objective starting point is seen as valid, while subjective starting point is not, therefore it doesent start from subjective point(like it does with Ti).
With this Fe Fi example, the subjective factor of Fe is not 'whats of personal value'(Fi), but the subjective impression of social feedback.
Also F isnt about humane factor(this is something you came up with in order to fit your views on typology), its an value judgment. Fe makes the value judgment based on social feedback(values of others), while Fi makes the value judgment based on whats of personal value.
