Not surprising that scrum works best for consultancies -- Scrum has just as much to say for how engineers should behave as it has to say about the people paying for the project should behave, and how to pretend to be that person when they seemingly abandon their duties. The sprint is also a product of its time. A methodology for shipping new features on a monthly basis is great when your competitor is shipping Excel on an annual basis. But the shorter the turnaround time for a feature, the less use there is in planning timelines. This is why the big tech companies don't have a unified process -- the process that works best for shipping operating systems is different than the one that works for shipping a mobile app, is different than the one that works for shipping a webapp. Any program office that tries to smooth out these wrinkles is hazardous to their wealth.
