Tons of major cities have been wiped out from fire in the early 1900's. But you have to consider how ill-equipped they were to handle fire, not to mention a total lack of research. Modern cities have working fire hydrants and buildings can have multiple fire suppression systems. Most of this is due to those massive fires happening. Here is NIST's report on fire resistance of timber structures (https://www.nist.gov/sites/default/files/documents/el/fire_research/NIST-Timber-Report-v4-Copy.pdf https://www.nist.gov/sites/default/files/documents/el/fire_r...). It includes guidelines that help increase the fire safety of wood buildings. This page (https://www.firechief.com/2017/03/14/are-wood-frame-high-rises-a-fire-risk/ https://www.firechief.com/2017/03/14/are-wood-frame-high-ris...) shows CLT has had testing to approve it for use in 6+ storey buildings in multiple countries.
