We do have Jean-Luc's line in Chain of Command: " That war cost you hundreds of thousands of lives... depleted your food supplies... left your population weakened and miserable... and yet you risk war again."
So obviously the war was a huge cost to the Cardassian Union, but perhaps not as big a deal to the Federation. Maybe those hundreds of thousands of lives were mainly lost due to starvation as Cardassia relocated resources to the war effort - while for the Federation suffered little - excepting a few very bloody border skirmishes (like Setlik III).
"Hundreds of thousands" seems to be lowballing it. That's about equivalent to the annual death rate in America from cancer or heart disease. As wars go, a death toll of hundreds of thousands is kind of mid-sized, something on the scale of the English Civil War or the Crimean War. Even the Korean War had more than a million fatalities, and the World Wars had tens of millions. On the scale of an interstellar civilization with dozens of planets and a population maybe in the hundreds of billions, a death toll of hundreds of thousands does not suggest a very massive war at all.
