Just use an airbrush? Or something else?
Back on days, when I started off with digital - it was something i really loved to do - paint fake lights on 3D scenes because my abacus at time couldn't render much else besides basic shapes with simple texture.
Now how you tackle that particular room would depend of your software - Like in some programs you may want to use blend mode, but it can be done without it.
I would actually not use classic soft edge 'airbrush', but very low opacity hard round brush - the most basic and classic one. Set opacity of the brush very low that, when you overlap, it also creates kind of subtle blend effect. Think a bit of ... let say watercolors. Where you build up trough very subtle lines most times. Using blend-modes can add a lot to your work, but for it to have true realistic impact the normal-layer light has to already look good and that you can do with low-low-low opacity brush. Learn 1st without blend modes. Light and fire are such of wonderful things to study!
On the example image - 1st you likely should have the glass painted and the floor done (no light effects) , and then make light on a separate layer paying attention to the areas, where light does not get to and keep strict angle of the "god ray" -effect. Later you can add some sort 'paper' material via blend mode overlays to mimic dust particles.
For a god-ray effect work well on a digital work, you also might need use the 'industry standard' move of downscaling which means you work on much larger canvas than you intend to show at end. Downscaling the image often makes light and shadow effect often look better, when lines get slightly blurred.
