I like this one from Hickok45. He has two videos, watch them both. These are probably the most thorough and instructive I've seen. He's cleaning a Glock but his advice is sound for your new Ruger also: get *ALL* the crud out, by all means. Use mildly-to-non-abrasive, non-destructive tools that won't hurt the plastics or metal. Use small amounts of your preferred solvents and *small and judicious* amounts of lubricant, and don't grease the thing up like Jimmy's Deep Fry Emporium. He's particuarly emphatic about the striker channel and my experience and other's with the SR9 has borne that out: you DO NOT want a lot of excess lube in the striker channel attracting deposits and gunk and gumming up the works. You don't want grease and oil all over everything. It's going to collect crud. Enough crud and it will impede the motion of the striker, and you will have operational issues from the trigger to the primer and beyond.

Also don't forget all the stickies by Josh Hearne in this forum. As always make sure before you fire your new SR9 that you field strip it and try to get as much of the factory packing grease out of there as you can. Josh's instructions can show you how to get into the striker channel. You don't have to do that right away, but you probably should within a few hundred initial rounds.
Take your time, learn all about the gun, spend some quality time with it when you get it, and you'll be happy. One tip I can give you before you get your gun is that the best way to handle the gun if you feel the slide serrations are sharp and the racking is "stiff" - don't whine, put a little more snap in your action, a little more velocity. I was surprised by the slide-racking effort at first but that was 99% inexperience and technique, and the effort does decrease after some use and time. Don't be afraid to dry fire the gun (with the mag. in unless you remove the disconnect) and practice slingshotting the slide. After you do that for a while and put some rounds downrange the effort will decrease and/or your training will increase to the point where you don't think about it, at least that was my experience. Also, I do not want to get in a war about this but I use the slide stop as a slide stop, not a slide release. In other words, I do not use it to release the slide all by itself 99.9% of the time. I did that from the beginning and because the SR9 was my first (well, second) pistol, I never had to "unlearn" anything else. So start that way and you probably won't have any issues with it, either.
BTW I didn't comment on the choice of lubricant because I have no experience with Militec. They have a procedure that they want you to follow, and I can't see how it would hurt anything as long as you use common sense elsewhere. I use Ballistol on the barrel only (like Hickok45) and also Hoppe's products. I'd like to see how a little Mobil 1 will do as a slide lubricant the next time I really clean the gun. I have a fine little collection of toothbrushes and other little brushes and things that I also use in my other life in the printing business.
Welcome to the family!
Wanted to get a good cleaning solvent. I ordered some Militec 1 oil and grease. Also, any good Youtube videos to show how to clean a pistol properly? This is my first one and I know too much is bad.
