Like what is my main role in society? What is my family (assuming I have two wives) like? How do I raise my kids? How violent is everything? I'm not a noble but I am fairly well off.
Please pick whichever civilization your most knowledge about.
There's lots to be said about the lifestyles of the elites in the Bronze Age, but I touched on this in What did being wealthy look like in the Bronze Age?
For the raising of children in Bronze Age Mesopotamia, see my response to What did the life of a Sumerian or Akkadian child look like?
