Great job on this, and great comments from your colleagues.
Keep in mind that you want to go beyond a category in the data (e.g. what was important in making decisions) to actually say what was important to people.
One thing to think about in deciding what themes to focus on is what is surprising? interesting? what did you learn that you did not know before?
For example, in a study we did of ICU family members, we found they viewed things as decisions that providers probably didn't, like which rehab facility to go to. And they felt these decisions were maybe more important than stopping life support, which they didn't see as a decision because they would never do it.
Re: reflexive memos, think about and discuss how your world view might influence how you read the data, and also how did the data impact you personally.
