I would go with hard science fiction futurism. You get to write your narrative future history of humanity and nothing about your choices are restricted to following the styles or decor consumerism.

For example, humanity has moved into thousands of 35 km × 9.1 km O'Neill cylinders with centrifugal spin gravity, mostly in cislunar space. We renamed the planet Wild Earth, and only a small scattering of indigenous humans choose to remain planetary caretakers. The age of scientific discovery has long past. Science is primarily an engineering corpus. Our primary technology is entirely biological, and in complete elemental cycles balance. All phenomenon of biological nature are accessible to us with a few genetic # inclue libraries and a few lines of code. We grow a banyan frame of a building and dial in our colors and patterns on living chitin walls, while more regal structures of ginkgo trees last nearly forever. Biocompute is a thing with the synthetic brayn. All is accessible with a complete understanding of biology.

Allowing your imagination to run freely in this space is therapeutic on a level that I find deeply satisfying, and dare I say hopeful. Getting others talking about this can create change. Futurism is anti dystopian. Many will try to call it utopianism, but I counter that they simply lack depth of imagination. The full spectrum and challenges of such a future creates a powerful lens for inspecting and critiquing the present. That is the best way I can imagine the experience of creating a space and the type of space that inspires positive conversations I want to share with others.
