Attention to detail is great, but don't worry about it more than you want to. If service weapon grade guns like the SP-01 required complicated maintenance to keep running, they would not fill their purpose.
For my Shadow, I spray a small amount of gun oil (NATO S-761, freezing point -57C so I don't have to worry about jamming in winter) inside on the parts that either move or get dirty while shooting. A drop along the rails, another in the breech face. A few in the chamber and barrel. A few to cover the large surfaces which collect residue, like inside of the slide and outside of the barrel. I let the oil sit and distribute itself for a while. Then I use fabric from an old shirt or sheet to wipe down the visible oil, and re-wipe forcefully until no more residue is coming off the surfaces and the feeding ramp is shining (other parts are matte so you don't have that kind of visual indicator...). Then I run a Boresnake through the barrel 2-3 times, which is the equivalent of a metal brush followed by patches. Once in every couple of cleanings I use matchsticks or toothpicks to dig dirt out of the corners of the breech face. And that's it. I don't use separate cleaning agents, grease, or anything else. Also, when I'm shooting more often, I'll clean the gun maybe once a week, not after every range trip.
Like everything else inside the gun, the guide rod gets a small amount of powder residue on it when you shoot. I'm about 99% certain it is not necessary to ever clean it. I still occasionally wipe it and the spring just because.
