...although the exact effects depend on your particular mix of
upstreams.  LOCAL_PREF trumps AS_PATH...

I severely de-pref long paths, thus [hopefully] giving those who
prepend their desired result.  A side benefit is this often
catches long-pathed improper redistributions.  I know I'm not
alone in this.  And one usually can adjust LOCAL_PREF via
community advertised to an upstream.

IOW: YMMV (YMWV if using no more than prepends)
