From the Nikon website for the D5300:

 

 JPEG: JPEG-Baseline compliant with fine (approx. 1:4), normal (approx. 1:8), or basic (approx. 1:16) compression

Is the reduction in file size due to binning, or something else?

 

Is it possible to bin the D5300 to increase the 3.92 μm pixel size for better well depth?

It’s the amount of JPEG compression. Depending on the compression level, the JPEG compression algorithm throws away details that, in its understanding of human visual perception, are not “important”.

For anything but the most basic astrophotography needs, you should never use JPEG but only NEF files.
