Even simple Sci-Fi like Matrix, Terminator or Mad Max for example is a nightmare in my opinion.
Getting or creating the assets, the renders and so on.
But it is tempting
Or perhaps a Snake Plissken style?
TBH, while I see a sci-fi movie here and there, movies and TV sci-fi is NOT what I enjoy. I am a reader. I have over 2,000 volumes of sci-fi, had to stop collecting, no more space, and, yeah, I refuse to separate myself from books I've read. Some of them 10's of times.
So, sci-fi, is NOT obligatory to be in space. There's a fabulously beautiful story that is set in the pre-historic times, and it is Science Fiction, the science that is fictionalized is Archeology. Then there are stories like:

That can be placed in any setting you want.
But, it can be anything. Anywhere. Anywhen. Sci-Fi isn't about the setting, is about humanity, in a kind of "What/if" question. Yes, the beginnings (called the Golden Age ) were mostly about Space exploration and the attempts of writers to understand what those new challenges meant. Then comes the New Age. Where some Fantasy elements were included, by speculating how they could scientifically be possible. So, while hardcore sci-fi is still considered about space, it is no longer a requirement. Science is NOT only Physics, or Chemistry, or Mathematics... human sciences are also able to be fictionalized.
So, when you say that assets are hard to find, no, you are limiting yourself. Sci-Fi doesn't really have limits.
