um lets see
Star Wars - a group of rebels/smugglers join a kid with powers to fight against the imperial expansion of a militarized government
Firefly - a group of rebels/smugglers join a kid with powers to fight against the imperial expansion of a militarized government
GotG - a group of criminals/smugglers join a kid with powers to fight against the imperial expansion of a militarized government.
In this one the Militant General (Ronan) and the Emperor (Thanos) are building a doomsday weapon (Infinity Stones) that can destroy a planet
Blakes 7, Stargate, Farscape.
Doctor Who sort of follows the premise of the Kid with powers fighting bad guys across space too, and Star Trek federation could be argued to be the founding of the Republic
So nope without the Star Wars tropes they're all pretty much vanilla sci-fi
