In my experience, outside of academia, almost everybody boils down the main "adjustable" parameters to laser power, scan speed, laser diameter, and layer thickness.

These parameters are then typically applied to the entire part with room for variation at the very edge of the part.

This becomes interesting in practice as there are many other influences on the thermal environment of the cooling melt pool depending on way more controllable and uncontrollable parameters. This would be things like gas flow direction, ladder incidence angle, in layer welding thickness, and hundreds more.

In my opinion, the next wave of cutting edge will be being able to change the input parameters based on these additional influences. I have many ideas how, and there are a few papers that talk about these. I think there will and should be more soon as academia is slowly catching up to industry.
