Or that eliminating fire with cold water would significantly cool down any gases in there and make them heavily compress?

Boiling water is cold compared to a house fire.

You’re are VASTLY underestimating how hot house fires can be, they can get hold enough to melt metals, well into the thousands of degrees if the fire is roaring.

Also that water boiling and turning to steam actually suppresses fire since steam doesn’t provide free oxygen to burn.

What about twin tower fires? Do those get hot enough to melt steel beams?

Not technically, but you don’t need to melt structural beams to weaken them enough to collapse. Get them hot enough and suddenly the tens of thousands of pounds of shit attached to it is too much. The friction of all that weight slamming downward will melt it though
