I found lighting figures with the background very difficult as Poser shows only a restricted image of the background in preview,  so I have tried another way.   Render the scenes with the selected background and use an AI background remover to mask the image.  Replace the background with the image but as a .jpg suitable adjusted, which should get you back to square one but now you have a layer of each which can be moved and adjusted accordingly.   It will only works for figures and I suspect the same could be done with two renders, one for the figure and one for the background.  Anyway this is what I achieved in about thirty minutes using an existing render.

Actually, that's not correct, you can manipulate the background image if you are strictly using an image and not an HDRI.  This is demonstrated here.  And if you set the background image to cast light, there will be ambient lighting applied to the render as demonstrated below:
