I am in a very different field so I am not sure if it's any helpful to you but here is what I do. Open PDFelement on the right side of my screen and Obsidian/Craft on the left. The idea is that my notes should be sufficient enough that if I want to review the material I don't need to open the textbook anymore. This means sometimes I copy snippets from the textbook to my notes, which is always properly indicated. Other than that my notes are basically my thoughts and ideas of how I understand the subject I am reading about. I take notes as I read and if I ever feel that I wrote too much I delete the redundant sentences. Longer notes are not always better so I try to find the right balance. The most important advice is that you don't want to rewrite the textbook. Seems obvious, I know. Focus on how you understand the subject and write about it. My notes are in a sense small essays that are highly inspired by the textbook chapters. As for some misc study tactics. My absolute #1 during my MA was setting a hardcore daily limit on how much I studied and during that time I made sure I am 100% focused on what I was studying. I quickly realized that being fully focused for 2 hours brought me vastly superior results than let's say giving my 60% for 5 hours. More time spent working does not equal better results.
