What are the most club-friendly non-fantasy RPGs for a weekly quarter-long campaign?

Looking for non-fantasy RPGs (no D&D, Pathfinder, or OSR, there is plenty of these everywhere) for a weekly 10-12 session club campaign. Ideally:

• Easy onboarding for mixed experience levels • Light bookkeeping and prep • Supports campaign-length stories

Genres like sci-fi, horror, mystery, or modern-day preferred. What’s worked well for your groups?
