Iron is only a touch higher than it should be. Try using a Fram Ultra oil filter for better filtration, the best filter around to catch more, so it might help some. The Fram.com website says you have to be careful which oil filter you get since they changed the oil filter thread size in the middle of the model year.

Then I'd recommend M1 AFE 0w
30 from now on (another walmart item like the fram ultra oil filter). That's 10% more HTHS viscosity for these slightly older engines and it could lower the wear numbers.
Your ending viscosity wasn't excessively low, meaning you could stick with 0w20 for a while and change to slightly thicker in later miles. I would go ahead and start using 0w30 now if it was me.
(Thanks to this site.) I have a stockpile of 0w20. It will be a while before I consider a 0w30.

On sale at Costco that week. Since that OCI I've used Idemitsu 0w20, and my last change a week ago I used Supertech 0w20. Maybe it's placebo but the supertech seems to run really smooth. I will likely run it to 7K and do a UOA.
