That is correct.  A big flashing warning would be a minimum.  Better still, measurement tools should be disabled if measurements will lead to erroneous values, or they are "corrected" behind the scenes to appropriate geodesic/planar values using a projection appropriate for the area where it is being used (a minimum for field workers for sure).   ...

If the measure tools aren't projecting/calculating in an appropriate coordinate system, but relying on web mercator data, then FAQ: Why Are My Map, Distance and Area Measurements Wrong When Using WGS 1984 Web Mercator It is useless for area and distance measurements.  So the reference should get you started and the basic properties of the projection and its associated coordinate system is not really the problem, it is that the tools for onscreen measurement don't reproject to a location appropriate conformal/area preserving/distance preserving coordinate system ...

I would have this check because there is an un explained paragraph in Calculate Geometry Attributes (Data Management)—ArcGIS Pro | Documentation The geodesic length and area properties use a shape-preserving algorithm. This produces highly accurate results that are not biased by an assumption that the input line or polygon features are constructed with geodesic arcs between the vertices, which is the assumption regarding traditional geodesic length and area. It might be worth reaching out to tech support to see if there is any support documentation explaining the difference ... View more

from Specify text for labels—ArcGIS Pro | Documentation A label expression can be either a simple single-line expression or a more complex expression spanning multiple lines of code and using the parser's programming logic. Arcade enables complex expressions by default. When using Python, VBScript, or JScript, check the Advanced check box and wrap the code in a function to enable multiline expressions. So you need to write a "def" ... View more
