I will show how I combine curtain walls and window families. Before that, I will mention something that is probably not new to you. Many Revit users use curtain walls to model complex and custom made windows like those shown bellow:

This is understandable because it would be very tedious to create new window family for every custom made window in your project. In construction, the key differences between curtain walls and windows are in their profiles. Still, some users create curtain wall mullions by using profiles which actually describe a window frame. This is how they give new purpose to curtain walls.

The downside is that they don't get much control over how curtain walls embed. The curtain wall families create just one simple opening (which may be appropriate for their initial purpose). On the other hand, window families give the ability to use multiple voids and tools for wall layer wrapping. Yeah yeah, no options for wrapping in the section view thanks to the program inconsistency, but this can be managed with some workarounds. (Btw, I didn't look at rv2018. so I apologize if they gave this option).
So, my question was "how can I get the best of both Worlds?" . I learned from nested families. Since a curtain wall is a system family, it cannot be nested. But, it can be positioned inside a window in a project. Ofc, to make this work, you have to uncheck the curtain wall option "automatically embed" as the Window family will create the opening.
Now, your question might be: how will this affect scheduling? You give the curtain wall a type mark which then you can use to exclude the particular curtain wall from schedules. When creating a schedule, add parameter "Type Mark", use "Filter By Type Mark" , select "does not equal" and write the mark.
What are the advantages of this?
First, you are able to use a window family with its parameters for scheduling. If you have a good window family, you will have tools for wrapping, optional head-space and all that good stuff. You will be even able to display how the air bridge is being ventilated in a wall....
Second, you will be able to model fast. With their grid lines, mullions and panels, curtain walls save your precious time....
