Fire departments generally love foam because while it does burn it fills entire spaces and prevents fire spread and limits exhaust of combustion byproducts (which limits oxygen intake on the other end). What would have been total losses turn into minor repair and smoke damage rehab. I'm still not a fan though.

In my (admittedly minimal) experience as a volunteer firefighter, “minor repair and smoke damage rehab” isn’t a thing once a fire is progresses handheld fire extinguishers.
Water causes a massive amount of damage, and you often need to rip apart walls and floors - with water sometimes joining the party - in order to ensure the fire is fully extinguished.
