What CMYK profile to use?
If you are just printing your work on an inkjet printer, or sending it a lab, this choice has no relevance to you. The CMYK profiles that you are looking at are only for commercial presses so unless you are having your work printed by a commercial (offset) printer you can set it to what you like - you will never use it.
For clarification, although your inkjet uses CMYK inks, to the outside world it is an RGB device. The RGB>CMYK magic happens in the printer driver and firmware.
