I'll answer my own question-in my case there isn't much difference if the Source settings are partial and the Advance settings are partial or if the Source settings are full and the Advance settings are full. At least in my case when recording to a Rec.709/ProRes file, problems creep in when the Source settings and the Advance settings are not the same. Setting the Source setting to partial and the Advance setting to full introduces a lot of contrast, while setting the Source setting to full and the Advance setting to partial results in the opposite-a clip that looks washed out. These comparisons are drawn against a clip of the same scene shot in BT.709/H.264 in camera. As I indicated in another thread, with just some slight tweaking to saturation both the limited/limited and full/full clips line up almost precisely with the BT709/H264 clip on a vectorscope in Davinci Resolve.
Partial it's value from 16 to to 240, full is 0 to 255.
How 8 bits is changed to 10 bits, source (8 bits) planner is copy to 10 bits and rescaled, rescale quality is software or hardware (directx change), recorder like ninja has own algorithm to this better or worse i don't know.

Thanks. I did a few more comparisons between the H.264/709 file in camera and both ProRes and H264 files recorded in OBS. I shot the identical scene (with a nice multicolored lamp in the frame that has a few colors that coincidentally nearly match the colors on the vectorscope) each time. Long story short the OBS recordings were all nearly identical on the vectorsope (the minute differences were not detectable on screen). So the 8-bit OBS H264/709 clip (using limited/limited settings if I recall) was nearly identical to the limited/limited and full/full 10-bit ProRes OBS clips. All three clips were just slightly more saturated than the internally recorded H.264/709 clip. Since the 8-bit and 10-bit OBS clips were nearly identical and they all required the same slight adjustment to match the internally recorded clip, I'm wondering if the difference in saturation is due to the 4:2:0 recording that the camera does internally vs the 4:2:2 stream that it puts out on the HDMI.

Anyway, I'm excited to be able to grade these D5300 clips in Davinci with 10-bit ProRes files.

D5300, send 4:2:0 as 4:2:2 over HDMI.
