Not sure about the others, but at least the Chinese "flood myth", the legend of Yu the Great, is qualitatively different from the Noah myth. It involves non-cataclysmic, recurring floods that the "government" wanted to control. There was no saving animals on a big boat and restarting civilization. It basically involved a big engineering project of directing water flow to where it's needed.
The Noah flood myths seem to describe floods of a much scarier kind, the kinds that have the potential to wipe out civilizations, as opposed to ones happening on a "fairly regular basis". Given that sea water levels rose tens of meters during the Younger Dryas (that's what google tells me at least), it seems conceivable that the movement of such massive amounts of water during these periods would have given rise to such stories.
What is common is that "everything" gets destroyed, a few survive to rebuild.
I'd go even further: there is no human habitat at all where floods are not dangerous catastrophes. The coast and alluvial plains trivially so, but mountains and deserts, too.
Edited for clarity
Also at some point in prehistory the rock formation that is now the strait of Gibraltar fractured and the Atlantic ocean rushed in and drowned the entire basin of the Mediterranean,[1] so that type of cataclysm has actually occurred, although before human experience
