I mostly read a lot about Akbar, who was a fascinating figure. His “official biography” is really well written, as is his whole concept for creating a new religion:
The Gurkaniyan thing was true for Babur but I don’t think it was the case for later Mughals.
The poet Ghalib, who was the emperor Bahadur Shah Zafar’s contemporary, considered himself a descendant of the aristocracy and referred to himself as a “Mughal baccha” in a well-known quote (sourced from his letters, I believe).
Fun fact: They called themselves "Gurkhaniye" and not "Mughals". It was a term mostly popularized by rivals like Marathas (which is also an exonym)
