Symbolic debug information, for dwarf2 is stuff found in .debug_info.
CFI and eh-frame are lower level than that.
Well, CFI is normally found in .dwarf_frame, which is at the same
level at .debug_info. There is also CFI in .eh_frame, but in general
only for C++ code (or code compiled with -fexceptions). Only on amd64
CFI in .eh_frame is generated by default.
