As I said, not everyone agrees, but it remains the majority opinion. i’m not sure how to fully answer the question(s) except to say that there’s logically a limited number of options. The evidence from cognate languages hasn’t changed much in 50 years, so there’s not much extra data to take into account (for those who even care or are aware of this angle). The biblical data itself is fairly sparse. IMO, the tricky thing is figuring out the distinction between “image of God” (which we are) and “image of Christ” (which we are growing into or progressing toward).
