Could enlightenment be characterized as self-confidence based on truth versus self confidence based on beliefs? The difference being that the enlightened are forever free from the state of cognitive dissonance? What is Creator’s perspective?

This is a good technical analysis of the considerations here. Enlightenment can be defined as "being in divine alignment" pure and simple. When one is in alignment, one will have an inner awareness and understanding of wisdom because that is a good working description of the quality of divine consciousness. The divine mind is fully informed, judicious, and aware of all the possibilities and can envision the hazards and risks with any enterprise and strike a balance to accept a reasonable challenge in order to add something new to the universe, but without risking self-integrity. In other words, to balance risk and benefit wisely so one simply will not get into trouble, having wisdom to work. In someone who does not, here again is an invitation to inner doubts and fears, and anxiety about where one stands can come into play and begin to cause a decline in happiness and effective functioning. If the negative emotions grow to a level where they become a detriment to efficient functioning and productivity, the average human is quite used to working under stressful circumstances and will keep going no matter what, but everyone has their limit and will have a breaking point when limits of tolerability are reached from a chronic ongoing source of stress or multiple stressors. The person in divine alignment with wisdom to work with will know innately how to strike a balance, again with risk versus benefit in anything they undertake, to not bite off more than they can chew, take on more responsibility than they are truly ready for, because they are not reacting to baser motives of greed or arrogance or ego, but truly factoring in what one can contribute with respect to the risks and benefits for others who may or may not be in a better position to be a leader or be better informed and more capable. The wisdom to know one’s place and know one’s capabilities will allow being judicious in volunteering and choosing any number of roles with respect to how well they fit the individual and their skills and knowledge base. This is why maturity is valued; what it truly is, in actuality, is the gaining of wisdom through life experience; that makes someone more stable and more balanced in every respect, including honoring the needs of others versus the self, so as to judge whether it is a time to perhaps sacrifice something personally for the greater good and be willing to do so. Too great a level of inner fear and anxiety will make such choices seem to be an outsized risk in many cases, that is why a well‑rounded person will have the attributes of self-confidence in good supply and the maturity and judgment that come from the gaining of inner wisdom.
