sRGB is fine for most applications. It's near to most monitors and printers that you are likly to come across. However the camera is capable of recording colours in a much wider range than sRGB, In fact some reasonably prices printers can produce colours outside the SRGB gamut.
However this is all fairly mute as you are considering shooting RAW ( well done) , as the original colour information is retained within the RAW file. So provided you keep the original files if you need wider gamuts then it's normally a simple method to reprocess the original image and select a wider colour space
