Thank you again for the kind comments.
This has come up a few times to use a different methodology for exterior walls vs the interior walls. Unfortunately, Revit doesn’t provide such feature, and the same method is applied to both interior and exterior walls. That said, you can use the methodology that is mentioned in the link below to offset all the walls outwards to align them to the exterior.
If you have walls with different thicknesses, then you can use the method that I documented here:
I should probably add a dedicated page for this topic with a single video that goes through all these options in one place.
