RAW vs. JPEG and artifacts

I just got my first Nikon (D500) to try to get better photos in low-light (indoor volleyball.) I am aware I also need to work on my technique and post-processing a lot, but I was able to sell my Canon 70D well and found a great deal for the Nikon, and wanted to try something new...

With Canon I was only shooting raw, with 85mm f/1.8 prime, usually wide open at 1/640 and manually set ISO between 1600 and 3200 in these badly lit gyms. Center-weighted metering and AWB. I have a few of those older photos in my profile here and at https://www.instagram.com/rimevs/

I got a similar lens for Nikon - 85mm f/1.8 G, same shutter speed and apperture, but I used Auto ISO and matrix metering.

With this particular shot I noticed something interesting. I was shooting both raw and jpeg to see the difference. The jpeg out of Nikon was pretty good - clearly over processed but kind of dramatic. Then I try to edit the raw version (14 bit, compressed) and noticed a weird fuzz between the elbows which is not there in the jpeg version. I made it even worse while removing noise, but still it is interesting that Nikon somehow completely removed it in the jpeg.

Regardless of this particular issue, would anyone use different settings in this situation? Auto ISO seemed to vary wildly from shot to shot, so next time I will try a fixed one, though I will also try the other metering modes.
