Does it have HDR PQ or HLG?

See if you can load a flat picture profile onto it to squeeze a little more dynamic range out.

If you're shooting outdoors, and have time to set up a shot, you can use circular polarizer filters, Graduated ND or Attenuator/Blender ND filters to keep the sky from blowing out.

In the context of an outdoor interview, you could use a Scrim Jim with various attenuations of diffusion to soften the light on your subject, but this reduces their luminance in relation to the background, so your background is effectively brightened, but you can set up an ND net backdrop to bring down the background luminance, provided you're shooting at a very shallow depth of field.

If you do a good job while shooting, I don't think there's a reason to do much grading, just a little highlight recovery, selective saturation, contrast, and sharpening.

With 10-bit, even a less "appropriate" transfer function will still probably let you linearize and do significant adjustments - IF you can recover the transfer function using something like https://docs.opencv.org/3.4/d2/df0/tutorial_py_hdr.html - see the Camera Response Function section.

Also of great importance is whether or not a wider gamut than Rec709 can be selected.
