Here are the two GREP styles (applying a “nobreak” character style to both) that I've been using for text paragraphs for a while:

[lu]+(?=[—–-])

(?<=[-–—])[lu]+

(That's a hyphen, en dash, and em dash that it's looking for. I like how you've added the apostrophe, but I wouldn't have gussed that ID would hyphenate before or after one.)

I suppose that instead of your [w|’] and my [-–—], we could consider [S], which would catch anything that's not a space.
