So I got a pretty good 3-4 cm scratch (deep enough that finger nails would get caught in) on my new car a couple of days ago and decided to try my hands at wet sanding with the Turtle Wax Scratch Repair Kit. Anyway, in my overzealous attempt at perfection (should have stopped after first round), I over wet-sanded the area, so that I now have a lighter colored blemish around the scratch itself. I'm guessing I went into the clear coat and any additional wet sanding attempt will simply enlarge the blemish. My question is mainly, should I leave it as is (with the cloudy blemish around the scratch, is there any possible future damage, i.e. oxidation, etc?) or should I just apply touch up paint to the entire area and leave it at that? The scratch is completely gone, now the blemish remains.
You sanded through the clear coat and went into the color coat , I would try a little of the car wax that is color matched to the color of the car and see if that will hide the blemish. Trying to make a spot repair using paint is something you better practice doing first on another car before you try it on your new one.

Sorry, but the bad news is to correct your botched attempt you need a body shop to repaint it.
Two things here.....
If you intend to keep the car until it dies then repair it as you want to or do nothing.
If you trade often the scratch will cost you more than a repaint in lost trade in value so get it fixed.

Please re-read my post. As it is now.......you're stuck.
Right, I know I'm stuck. Anyway, if I do nothing at this point, will the paint/metal be fine? My primary concern right now is will this lead to peeling and rusting. It's slightly unsightly, but not too noticeable and I can live with it (albeit somewhat begrudgingly).

Just brush a light coat of clear and move on if you don't want to fix it right.
You've sanded through the clear coat. The underlying base coat is porous. There is likely a sealer under the base coat that will provide some protection, but you have opened it up so that moisture can get through. Yes, eventually the metal will corrode in that area.
Rule of thumb: If you can feel a scratch with your fingernail, you won't be able to sand it out.
