If one wants to look at sequencing, which you make a reasonable case for, off hand, I’d suggest Temperance/Self-Control.
I’d do so on the grounds that the gifts of the Holy Spirit are traditionally sequenced Fear-Piety-Knowledge-Fortitude-Counsel-Understanding-Wisdom (the Fear of the Lord is the beginning of Wisdom), and that Fear is traditionally associated with the Cardinal Virtue of Temperance. Piety is associated with Justice.
One cannot begin to tackle difficult things well unless one has some self-control and some idea of what is just. Without these, one ends up looking like Sampson.
In view of the previous mention of humility, which is in many ways foundational, I ought to note that Temperance, as a Cardinal Virtue, includes humility, which is technically, if one digs deeply enough, an accurate and proper love of self (which includes a realization of one’s proper relationship to God).
