if FTL travel were possible we probably wouldn't exist. Whoever came first would probably colonize the Universe and sterilize it of competition
FTL doesn't necessarily mean infinite/instant travel. Also the scenario you propose could be part of the Great Filter, and we just haven't been culled yet. Or FTL civilizations tend to get so large they fracture & turn to in-fighting or encounter other resource bottlenecks that limit exponential expansion.
Or C is the law and going FTL spawns a cosmic traffic cop like the meatball head things in Rick & Morty.
Or FTL is simply impossible, but perhaps not constant and various factors impact the local C
