The genre is usually divided into "soft" and "hard" fantasy.
Cyberpunk is generally considered hard fantasy, as is stuff like The Expanse or Interstellar.
Star Wars is unabashedly soft SciFi, it's a straight Fantasy story in space.
Star Trek is a half-breed - it pays some lip service to scientific "plausibility", but much of it stretches that envelope beyond the breaking point. Scientific accuracy was never the point of the series to begin with.
