I'm confused on what all is needed to do a swap on my 2010 Challenger R/T (A5). I currently have the open differential with 3.06 gearing.

I found a 230mm 3.90 gear differential from a M6 2015 Challenger. I was originally going to swap the entire rear axle hub to hub, but I'm finding it might be cheaper to just buy the parts I need specifically. What all would I need? Just axles and differential?

2015 and newer not going to work for your 2010, you need to find a 2009-2014 Getrag 226mm. They are all limited slip and can be had with 3.73 or 3.91 gears. Not sure on all what's needed but assuming you will need at least the rear and halfshafts.

Yes, the cradle is different. But I guess you could swap the cradle too and then it would work. Exhaust I think might need slight mods near the rear. Might be the way to go, the ZF is a newer and maybe better rear than the Getrag and there's lots of ZF's around.
