I am a TOTAL sucker for robots (and aliens, lesser so) developing sentience and discovering/exploring their humanity. Tangentially related: stoic types showing glimmers of emotion and having to process strong feelings for the first time.
e.g. Data from Star Trek: The Next Generation, The Transformers franchise.
Interestingly, I don't have a lot of interest in writing those kinds of stories right now, but I sure as heck love consuming them.
