Service Area polygons are jagged

In support of fire department deployment planning I'm generating Service Areas with the "Ready to Run Tools" in Pro 2.4.1.

SETTINGS: Not Overlapping, Rings, Standard Detail, 300 ft clipping

I've post-processed the results by clipping them to within 300 feet from my local roads dataset (to get rid of bogus fills in areas without roads).

PROBLEM:  In an area that contains a divided roadway the polygon boundaries are unacceptably jagged (see screen shot).  

1) Is there any way to improve the appearance of these polygon boundaries?  I've tried the "High" detail and that doesn't appear significantly better.

2)  I'd REALLY prefer to sidestep these polygon issues entirely by having an output type of "line", rather than polygon.  It appears this is an option that went away; is there any plan to bring that functionality back in Pro?

 

To speak more broadly about this, it appears that the "Generate Service Areas" tool really works well if you are in a large urban area with regular street patterns, but has many problems in rural areas when it comes to the details of polygon generation at a fine scale.  Filling in areas that are surrounded by roads (like a big lake) and creating these jagged polygon boundaries create a problem of perception when I show the results to customers. If the results look weird, the customers doubt the accuracy of the result.
