I came across the Strafe soundtrack, and it sounded like a visceral cross between Underrail apocalypse mood and Cyberpunk synthwave.
Sorry if this is totally off-base, but I think ToyTree (creator of Strafe soundtrack) could make something incredible with your world that would play off of the mood of the SGS base, Protectorate, or Scientific themes. It looks like he's worked on other games too.
