Okay, I see you have modern fantasy as high on your craving list, and I have a concept for you, meshed with the sci-fi/cyberpunk idea.

So, you have multiple planets, but they're not necessarily like, space planets. They're a bit more like, islands floating in the space-like ether, different realms from which the different fantasy races hail. Futuristic technology is powered by magic, and travel between these realms is very similar to space travel- but eldritch horrors and magical anomalies lurk in the space between, rather than black holes and asteroids. On the planets, or different realms, or whatever you wanna call them, perhaps some are vibrant utopias of technology blended with magic, while others are dystopian industrial wastelands where factories produce these technologies, some are wild elemental frontiers, and some still are nearly apocalyptic hellscapes where the planet has been harvested of its magic. We could make a story on whichever of these we chose, and if the story started to get stale, perhaps find a way to just... go to a different realm.

It's not a perfect or real in-depth idea atm and I don't know if it would scratch your itch. But, it could be a suggestion.
