In fairness, seasons and varied terrain aren’t guaranteed.
Of all the bodies in the solar system, only Earth has such a wide variety of landscape. Mars is rocky desert or rocky desert with canyons. Pluto is ice ball or rocky ice ball. Etc.
Also, if humans were colonizing earth from outside, we would probably just build cities on the river deltas and skip the less habitable spots. Stories set here would then just be cityscape or river delta, even though the ice caps/mountains/jungles/deserts still exist. Colonized worlds will have different population distribution that organically settled ones.
The Kepler program found a lot of exoplanets and has categorized them generally as Hot Jupiters, Cold Gas Giants, Ocean Worlds & Ice Giants, Rocky Planets and Lava Worlds.
If you ignore the gas giants because there’s no surface to land on, rocky planets (and maybe desert planets) would be extremely common. Water or ice planets would also be incredibly common. And, if you’re really unlucky, you might end up on a lava planet – one that’s small and very close to its sun.
What wouldn’t be common are things like an entire planet that’s a swamp, or an entire planet that’s a forest of Earth-style trees. I’m sure it’s entirely possible that on some planet there’s a life-form that becomes the dominant form and that looks vaguely like Earth-style trees, but not the kind you see on a typical SciFi show filmed near Vancouver.

Some Sci-Fi planet types are reasonable.
