ArcMap - Flat Environment v.s. 3D Environment

I am using ArcMap 10.4.1.


I have been learning about the subject of coordinate system concepts such as datums, transformations, projections, maps, grid, ground, etc.  While developing practical exercises for myself, I have come to the realization that ArcMap may be my only resource for properly transforming and projecting between different coordinate systems.  For example, I learned that AutoCAD does not really think in 3D such as the case with interpreting a true geographic coordinate system.  In fact, the world WGS84 datum would be visualized in AutoCAD as a flat plane, even though it is not projected.  So locating points and transforming, for example, between a State Plane coordinate and WGS84 is not possible.  However, I assume the ArcMap software is not working in a "flat" environment like AutoCAD, and can correctly interpret between a 3D Geographic coordinate system and a flat State Plane projected coordinate system ?
