For future boards, I’ll definitely only use the 50ohm trace width for 50ohm traces, in which case a straight sed search/replace will do what I need.  But in the meantime, any recommendations for doing a batch modification of the trace width of a group of selected traces?

If you have selected one possibility is to paste into other design and change them there.
