AFAIK, Visio has never had a learn as you go functionality. I'm surprised that Sketchup16 has this. What constitutes a typical routine behavior?
Visio has enormous flexibility and broad spectrum of application. I think comparing Sketchup and Visio is like comparing apples and oranges. If Sketchup meets your needs, Visio is probably wrong product and pretty much overkill. But, if you're looking for a corporate wide app that diagram floor plans, workflows, planning, etc, then, Sketchup is probably wrong, and Visio the better choice. I would recommend V2019 over either V2013& V2016.
As for standardization, Visio allows you to create templates that configure Visio for specific tasks. It does come with many such templates out of the box. More with Pro version than Standard. But any drawing made in one is compatible with the other. And, of course, there's compatibility with other office products.
