You can create a preset for the exposure module and define rules when it kicks in. For example based on the camera manufacturer, focal length, iso, etc. I use that to increase the default exposure compensation with my Fuji. I deliberately underexposes to prevent highlights from clipping. So I usually want a +1.25 exposure compensation. Likewise, you might want denoising on for high iso files.
You can organize modules into profiles and simply hide all the ones you don't use. The default profile hides some of the deprecated or display referred modules. You can change this.
White balance indeed has a deprecated variant for display referred and a scene referred one that works completely different that you typically use together with color calibration (which is where you should do most of your color correction, including color temperature changes). The reasons are mathematical and beyond me to explain properly (Aurelian does a great job on his Youtube channel). It boils down to not throwing away the baby with the bath water in terms of rounding errors accumulating and switching color model (to the one used by your display) too early in the pipeline. It might look pleasing but then it bites you when you want to tweak tone or do other things. This is the whole point of working with the scene referred modules.
Having all the legacy modules around is indeed somewhat confusing and Aurelian solves this in Ansel by hiding all the deprecated modules now. They are there for legacy files still.
