Just because standards have been developed, does not mean they were developmentally appropriate. Several years ago I participated in a "bulletin board" that covered education topics. A middle school social studies teacher had been on the most recent (at that time) K-12 Social Standards committee for the state of CA. He reported to us that the committee began by asking the college level instructors and professors who were on the committee what knowledge they hoped incoming college freshman would bring with them. Once the committee articulated what graduating seniors should be able to know and do in their discipline, they built standards down from there. The project endeavored to plug skills into the K-12 standards, but was not concerned with what may or may not be developmentally appropriate for the age and grade level. It was just creating standards to fulfill the wishlist of college professors.
Alabama should be added to your list, though they're doing a strange mix of both lowering at 3rd grade and raising at 4th grade. See this article: https://www.al.com/educationlab/2024/06/shifting-terms-cut-scores-complicate-alabama-3rd-grade-reading-efforts.html
