I don't have a lot of personal experience, however, our clients have the same wide range of use. Some put everything in them, others just a few document types. Since every document has a retention schedule (even if it is a "live" document that isn't ready for archival) it can be really hard to determine where everything should go. No one likes to drag and drop documents from "manila" folders to RME folders when they are ready for archival.
If you run everything through a Transparent Records Management workflow, that makes things a lot easier. The difficult part is identifying all of the different document types and which record series they need to point to - then having to build a parallel manila folder structure for your day-to-day users to look at. Lots of configuration up front, but it makes it a lot easier to have everything filed under Record Series if every single doc type is being run through a filing workflow.
