I just use the default setting. I can’t use any others because an accident with a tube of superglue and my camera has left it glued on default settings!
The easiest way to improve the photo quality (becuase mine are awful at first as well) is adjusting the image on photoshop afterwards.
My current fixup routine is to adjust the levels to get the lighting right, add a couple of gradient maps to improve the colours and then reduce the size by 50% then use unsharp mask then soften any areas with excess noise
