Looking for a rules light science fantasy RPG

Science fantasy stories are my jam so I wanted to try and run a game for my friends. Looking into it, Starfinder 2 had everything I wanted in terms of tone so we tried the playtest but I had a lot of trouble wrapping my head around core systems and my friends thought character creation was a bit too much. I then looked into 5e's Spell jammer. Again, tone was right, rules were perfectly light, cgaracter creation was relatively simple, but the lack of spaceship combat or any unique mechanics made it seem hollow. So any recommendations for a system? Thank ya kindly
