VSS: https://github.com/tianocore/edk2/blob/bf0bdacdd6f6cdd2e9ac5db14b6daf19a5a5bd57/MdeModulePkg/Include/Guid/VariableFormat.h#L87 FTW: https://github.com/tianocore/edk2/blob/bf0bdacdd6f6cdd2e9ac5db14b6daf19a5a5bd57/MdeModulePkg/Include/Guid/SystemNvDataGuid.h#L62 FDC: was reverse-engineered, so I can't provide any references, but it's mostly a wrapper around VSS2 storage used for SecureBoot-related authenticated variables.

As for how to restore defaults, it depends on the particular image, so I can't provide a generic answer here. If you can upload an image you are trying to restore the defaults for, we can continue this conversation.
