In short: He blew up/disintegrated, Cadance said he wouldn't return, it looked different than when he was turned to shadow, and he was hit with his greatest weakness and the only thing that can defeat him. Was it ever mentioned that Maleficent died when Prince Phillip stabbed her? (beyond Flora saying "Let evil die and good endure")

I think officially he's dead and will not return, but people who think he survived can still write/read fanfics of his return (though they'll have a time coming up with a final defeat for him if he can come back from that, because if he can return from that there's no permanent way to stop him). IMO Dumbledore had a higher chance of survival even after JK Rowling said upfront that he's dead

Sure, we see his horn, but we can assume that it and the other pieces of him eventually dissolved midflight. (When Celestia shatters those dark crystals in the palace, was there anything left of them?)
