Here's the FEMA report

This link is to a conspiracy theory site, with inline comments by conspiracy theorists! The link to the original document at the end of the page doesn't work.

And this is the NIST report

This is a news piece about the report, not the report itself. It contains a link to the report. In the report, page 33 begins the executive summary. As opposed to the summary you posted, it's isn't optimized for sounding ridiculous, while acknowledging the fact that similar fires never collapsed similar buildings before, etc.

Factors contributing to the building failure were: thermal expansion occurring at temperatures hundreds of degrees below those typically considered in design practice for establishing structural fire resistance ratings; significant magnification of thermal expansion effects due to the long-span floors, which are common in office buildings in widespread use; connections that were designed to resist gravity loads, but not thermally induced lateral loads; and a structural system that was not designed to prevent fire-induced progressive collapse.

Within the building were emergency electric power generators, whose fuel supply tanks lay in and under the building. However, fuel oil fires did not play a role in the collapse of WTC 7.
