Super Earths are easy to find and super common but I am almost betting the most life will be found in gas giant moons. Even though we don’t have any gas giants in our own system that have Earth-sized rocky moons, each one of ours has half a dozen “almost-there” moons. A civilisation developing around a gas giant with multiple habitable and easily accessible moons would be very interesting.

Magnetosphere of planet like Jupiter or Saturn is the most radioactive place in solar system... Also energies (delta V) needed to travel between Jupiter moons are greater, than those needed for travel between solar planets.

I thought Saturn was mostly benign. My hope was that a magnetosphere would protect the moons from the early outbursts of the red dwarf.

That's surprising. Found this nice map [1] and the numbers are really disappointing. ~15 kps from Titan-to-Iapetus sucks (even though it's ~4 kps less than Earth-to-Mars). At least the distances are smaller...
