Early versions of Stellaris had something similar, but reduced in scale- it’s a 4X grand strategy where you’re basically controlling a spacefaring species you create, if you’re not familiar with it.
They did away with multiple FTL systems at some point, but early on in the games lifespan when creating your species you’d pick between hyperdrives, wormholes, or warp iirc.
Hyperdrives were basically Star Wars style space travel- predetermined FTL ‘roads’ in space that you can travel along.
Warp was ‘the ship teleports from where it is to where it’s going’.
Wormhole was the most interesting one to me, because it used giant ‘hubs’ you’d need to build in space to… well, make a wormhole from the hub to wherever the ships were trying to go. The downsides were that you had to build hubs and they were expensive, and you could only actually leave from the hub itself which had a limit on how many wormholes it could make. The upside was that it had dramatically better range than the other FTL options so you could build one on the borders of an enemy and then basically show up wherever you wanted.
Tbf, you can weaponize a lot of methods of FTL in a pinch.
In Mass Effect their guns literally work on the same fundamentals as their FTL, just scaled down.
40k’s Warp… well, it’s where Psykers get their power from so every space wizard is kinda weaponizing FTL at all times if you squint. The warp itself doesn’t need weaponizing, but you probably could.
Stargates just sort of… disintegrate things that are in the way when they open. I can’t remember an instance of them weaponizing that, but I’d be shocked if it never happens.
