I was too specific in this idea:
https://community.esri.com/t5/arcgis-pro-ideas/use-regional-date-formatting-and-spelling/idc-p/14784...
New and less specific idea:
Use device locale for all spelling and formatting in Pro.
One example: use locale spelling for units globally rather then having users only set spelling per project.
Incorporate this concept in current and future functionality in Pro.
