Your opinion is a very detailed review of the subject that I tend to agree with as I understand it. I have seen the overall difference cast as the difference of faith-based thinking compared to reality-based thinking. A sort of idealism opposed to pragmatism.
I would say that both mythic and scientific modes of thinking are both "reality-based". They are just different perceptions of reality. As I said before, it is literally different realities the two different spaces create for the participants.
One could think of it in terms of our own personal experiences growing up. It's all the same physical world, but how it is held in mind and experienced amd understood by us at different stages of development in our lives radically changes. The world, or reality, when I was 16 was a radical shift of reality contrasted with when I was 5 years old. And again when I grew into my 20s, then 30s, and so forth. Of course that change was not due solely to biology, because there are plenty of fully mature bodies in their adulthoods who are still 13 years old emotionally, or cognitively, for instance.
As far as the mythic-literal stage goes, I would not call that "faith-based". Faith is a different thing. It doesn't meaning "believing without scientific evidence", which is how it gets distorted in meaning within rationalistic terms, considering it to be part of our history's religious past. Faith exists at all stages of development, including the rationalist stage. Faith, by definition, is not cognitive. It's a heart-based, sense-based, intuitive-based set of eyes.
A good way to understand this is this. The eye of the flesh. The eye of the mind. The eye of the spirit. Each is a different mode of perception, and each of those three modes of knowing are found in each of the stages of development; archaic, magic, mythic, rational, pluralistic, integral. Those three are are, in my opinion, the balancing arms of our humanity, in each of the stages of development.
To put that into context, think of those like parts of your own body, like your arms, your waist, and your legs. I practice Taijiquan as a mental, physical, and spiritual discipline. Each of those, body, mind, spirit, are like the arms, waist, and legs. Everything is interconnected, actively engaged, and moves as a whole, each providing counter-balance and structure so the form is light, effortless, and powerful all at once.
It takes far more than just being able to punch really hard (compare this to having a really sharp mind, or science). It takes the centering and grounding of energies (spirit) to focus that movement to exponentially more powerful action than just brute force alone (science).
I'll just share this here because it inspires me, and metaphorically it captures visually what I am saying. I believe we in a modernist world with its enamouration of the sciences, neglects the rest of ourselves, which would otherwise create a more powerful, connected, and dare I say, divine reality for ourselves at this stage of development. Just watch this form and imagine it as how we live our lives in daily life. To do that at this level requires a strong integration of all of these areas of life, body, mind, and spirit.
So back to the mythic stage as a whole. There are plenty operating at the mythic stage who do not have faith at all. The "believers" are using their minds, not their hearts or their intuitions. In fact, this is one of the big problems with religion is that what it is calling faith, is actually just belief.
So the mythic stage is not the faith-stage, which you grow out of and become a rationalist. Faith itself actually has stages of development itself, and someone at the rational stage, may well be at the mythic stage of faith, which is unable to understand the meaning of the symbol apart from the symbol, seeing them as one thing fused together. If it is not true factually, then it has no meaning.
This is what you see within a lot of modern atheist's rejection of religious myths as "just myths". That reflects a stage 2 faith, IMO. "If it's not literally true, it's not true at all".

What you identify as pseudo-modernity fits in with the differences in the way of thinking and brings those into alignment with the practice of fundamentalism cloaking itself in a disguise of modern science and rationality.
It also disguises itself as faith in the guise of religion.
It's really just simply anti-modernity and pro-traditionalist, and religion is the excuse because of common identity. None of that has to do with actual faith.
