I think you have a misconception. The name of each string (F7, B9, EF, etc) is only for use by the programmer and the compiler. It does not exist in the code, and cannot be used to reference the string. strlcpy_P needs the actual address where the string is stored in PROGMEM, not the name you have given it.
You could put the eight strings into an array, and save the array index in EEPROM, otherwise you will need to know the actual PROGMEM addresses where the compiler is storing the strings.
