Speed of light is actually quite an advantage, in theory at least. Speed of light in optical fiber is quite a bit slower (takes 50% longer) than in vacuum.

Not really. Fiber is more 2/3 of free space propagation and that puts the break-even point of direct fiber connection vs LEO up- and downlink at a geodesic distance of about 12000 km. So, for most data centers you want to reach a fiber is the better option.
