Ursula K. LeGuin’s Ekumen (Hainish cycle) stories have a fascinating take on “human”.
Humans on Earth are transplants from an ancient spacefaring race from the world Hain, and we’re not the only one. The Hainish are explorers, colonizers, and genetic engineers. Her novels and stories describe over a dozen distinct “human” races (to use the Terran word), from furry 3-foot tall forest dwellers on Athshe whose culture is entirely based on dreaming lucidly without sleep; Gethen, where the “humans” are genderless until they enter into something akin to heat, at which point their bodies switch to opposed genders and they make a baby; or Seggri, a place where the natural gender birth ratio is 16 females to every 1 male, and females dominate society. (Men are basically boy toys and sperm donors.)
She thought a lot about gender issues and her various Hain-descended human types reflect that a lot.
A number of James White’s Sector General stories are written from the perspective of nonhuman characters interacting with the human characters.
Pandora’s Planet by Christopher Anvil is written from the viewpoint of aliens who conquer Earth, only to have a terrible time keeping control of it and an even worse time when they realize that their problem is because humans are genuinely more intelligent than they are. Pretty funny novel, actually.
Ranks of Bronze and some sequel stories. They are written from the human perspective and don’t really fit this thread, however.
Humans in the movie Titan A.E. are mostly regarded, after the destruction of Earth (A.E. means “After Earth”), by other races as worthless refugees, thieves and sneaks.
