Just getting into reading for pleasure, looking for more great sci fi or fantasy

Recently I have read Dune and then the His Dark Materials series and absolutely loved both. Looking forward to some similar type of stuff that has the following traits that I found to be present in both series:

-deep and believable world building

-complex characters with complex but followable motives

-gripping sense of grand adventure

-big themes that reflect on our humanity/society (religion, morality, power, search for meaning, etc)

-when I read both of these I felt like I was reading something important and groundbreaking

Any recs that aren’t necessarily sci fi / fantasy are welcome as long as they hit some of the above. Really just looking for something gripping that makes me think “wow this author is a genius, and I can’t put this down”
