How'd you get the Dof so clear and the lighting so good?
Not an expert in lighting, but all I can say is that you have to tonemap it. Lighting in Daz is inaccurate unless tonemapped. I may be able to share some tips:
  1. The default 0.25 burn highlights already overclips the brightness. In some cases, 0.25 works (e.g. plain color background with multiple points of light source, i.e. a studio shot) but if you're shooting indoors/outdoors, never go beyond 0.15. If needed be, reduce crush blacks to lower black clipping.
  2. Fun fact, if you set burn highlights to 0, you're getting almost the equivalence of Blender's AgX/Filmic AgX without the color correction.
  3. Daz's default values for its camera are inaccurate while corresponding to a full-frame (35mm) camera - use IG Photographer's Toolbox: 35mm Cameras instead
  4. Tonemap your scene to get a more accurate GI. Daz default exposure make it as if the light path decays too quickly as it travels. Increase the exposure by tuning shutter speed, f/stop, ISO and/or cm^2 factor and combine with (1). Note that, increasing the exposure does not mean increasing or decreasing the "exposure value" property; you should be making the entire scene brighter by tuning the 4 properties that I've mentioned
Understand how a camera works (particularly full frame), and you'll understand how to roughly tune (4), and also be able to get the DoF you want via the camera properties (mainly the focal length and f/stop).

Hello, could you expand this part a bit? Would you recommend setting burn highlights to 0 for more accurate results, even if the scene isn't being overexposed at 0.25?

Nope, setting burn highlights to 0 does not mimic a more accurate result here, it is not properly color corrected for photorealism hence "AgX without the color correction". In any way, Blender's AgX/Filmic AgX is vastly superior.

The sole equivalence here is that both AgX/Filmic AgX and burn highlights=0 is fitting more dynamic ranges into the scene. However, AgX does clip some amount of brightness to retain photorealism, while setting burn highlights to 0 allow virtually unlimited dynamic ranges, which is NOT realistic to the eyes (as well as cameras).

IMO follow your artistic instincts. Depending on lighting conditions, 0.25 may work fine. If it doesn't that means lower the burn highlights to reduce unnatural clipping.

As an example, 0.25 burn highlights with multiple light sources
