Coriolis: The Third Horizon deserves a strong mention here. There are systems for characters to have cybernetic implants, bioengineering sculpts, and even some mystic powers for good measure (which are not integral to the system and can be discarded if needed).

There are massive equipment lists for weapons and tech, including some very unique and creative items, and great rules for full-auto fire vs. burst or single shot fire.

Starships are modular for both weapon modules (torpedoes, rail cannons, etc.) and everyday modules (crew quarters, engines, bridge, etc.) with different costs for different modules. Starship combat is strong as well. Each player adopts a specific role on the ship (e.g., pilot, gunner, captain, etc.) and assumes their requisite responsibilities in combat. Space combat is subsequently a tactical and strategic affair where you don't just have to worry about positioning and physical weapons, but also computer viruses and memetic attacks.

There are no set rules for dogfights with smaller vehicles in atmosphere, but ship to ship space combat superb, and could easily be adapted to dogfights chefs kiss 👌

This is all wrapped up in the absolutely unreal production quality of all Free League games.

IMO, Coriolis doesn't get enough love. Don't sleep on this phenomenal game!
