The answer to this question will be individually different. It depends very much on what I like to photograph.
Since I'm a big fan of fast glass, simply because I need it for some occasions, I won't get away with a tiny lightweight pancake. That goes as well for my Fuji stuff - but here the sensor is a limiting factor in terms of acceptable noise. My expectations of noise up to ISO 25.000 and above are not super high, but here the Fujis don't have much to deliver. Therefore bigger sensor, therefore bigger glass. For someone who is mostly in landscapes, the glass needs to be great for the maximal print size - but not fast.
Next thing: I don't like zooms so much, mostly because they are a tad slower than primes. With primes, I need to crop. With crop I need to have a bit more resolution from the sensor.
One could say, take a zoom and use VR, but that won't do for action indoors with available light, except I choose a motion-blurred shooting style - sometimes I do, but I also love to be free if I do it blurry or sharp.
