Well, the typical wooden buildings you're probably thinking about (ie, suburban housing) would be terrible and burn completely. If you take a look at their construction, they use relatively thin pieces of wood both for structure and walls. CLT or Mass Timber buildings are very different, there's basically a crapload of wood and it is very dense, so dense it can't burn well because oxygen can't get to it very well. It is essentially the difference between trying to burn kindling vs a single large log.
