Another factor to keep in mind when picking fill patterns: dimensional stability. As the fill cools down and shrinks, it will pull the walls in where they are attached to the infill. That is why fancy fills like Gyroid exist to give generally even pull and support in all directions without long straight stress lines in any particular direction.

A good rule of thumb is to use Gyroid unless you have a very specific reason not to. If you're just looking for faster prints, it's almost always a better idea to reduce Gyroid infill density than to try and tweak infill geometry, due to it's near-homogenous mechanical properties (outside of inter-layer delamination that is unavoidable for FDM).
Exceptions include cases where you intent to infiltrate the infill volume after printing (e.g. filling with resin or grout), where Gyroids two separate watertight cavities could be an issue. Or where you are happy with near-zero infill density but still need to support a highly undulating top surface, in which case Lightning infill is likely the best bet, as Gyroid would leave some small top layer sections that hang 'below' the ultimate top surface unsupported.
