Based on my understanding, a highly preferred Si would entail a greater level of entrenchment in physical reality, with less time spent daydreaming and in one's head. I find that the opposite is true. It would also imply a higher ability to remember and sift through detailed data. Si users in Jung and MBTI also tend to be unquestioning and to an extent, bureaucratic, when I am anything but.
Plus all of that stuff that you didn't bold.
