Well, not specific lighting tools, but what render engine are you using? I switched from Physical to Octane and having real time feedback made all my lighting better instantly. Now I mostly use Corona, and find its native area lights, with it's post processing during render (bloom, glare, exposure) and denoiser have made my lighting better much more then a GSG tool or prefab studio setup kit every did. Corona Lightmix also lets you adjust any lights level and color as you are rendering or after it has finished rendered.
Redshift looks very promising with volumetrics and atmosphere. Arnold has a beautiful lighting system and good atmospherics too. Maybe experiment with some renderer trials and see what that does for you.
