Keep in mind that our current instruments are not really sensitive to most exoplanets that would be interesting for a sci-fi setting.

Current instruments are mostly good at finding large planets around small stars, we are basically blind to earth-like planets around sun-like stars.

See e.g. https://www.nobelprize.org/prizes/physics/2019/queloz/lectur...

That's a very good point! And an opportunity for game worlds; extrapolate those blind spots by assuming small planets and planets further out from their stars are more common than what's been confirmed so far.
