X-55 has a yield of 200kt

Sounds too big, that's probably the nuclear version. As for X-22:

Search results are oddly quiet about the yield, but I was able to scrounge some evidence. So X-22 has a 960 kg warhead in the newer variants, and 630-900 kg for the older ones. During the tests, the missile left an up to 22 square meters hole in the target (mock air carrier), while the shaped charge burned through the bulkheas for up to 12 meters.

FAB-500 bomb has, as the name suggests, 500 kg warhead (it's a simple bomb, so no fancy bits, just the warhead basically). FAB-500 allegedly creates a crater 3m deep and 8m wide, with a 150-250m damage radius (sources differ). That would be shards and blastwave.

I daresay the larger X-22 would have at least as large area of damage. It was designed to be used against fairly tough targets (carrier ships), so it's somewhat less of a "kill everything around" type. But with a warhead this big? We can do the math.

Side note: searching this stuff on Google specifically yields ukranian resources. I'm sure there's no bias.
