In QGIS 3.10 (Latest LTR) there are several unit types, see image below
What is the core difference between those units, in sense of their visualization behaviour on the Map?
What I noticed by so far, that some features do not always work with Millimeters, e.g. "Geometry Generator"
and therefore you somehow need to switch from one unit to a different one.
On the other hand, you may work with a map, for example in a Print composer, and furthermore, such unit change can cause a huge impact on your visualization outputs.
Hense, I am looking for some kind of transforming strategy/approach that can lead me to the same visualization outcome but with the application of various Units.
Perhaps someone can refer me to any kind of explicit source with explanations.

Geometry generator
), units refer to the underlying coordinate reference frame (e.g. units of CRS). when you are styling (visualizing) your layers, units refer to screen/canvas dimensions (Millimeter
,Inches
,Points
); within that set of units, however, you can choose to have sizes in reference to the geometry level (Map units
,Meters at scale
) that are then translated to screen dims
