I'd like to add a laser/light to my M&P Shield 9 EZ, but I'd prefer it be short enough so it does not stick out beyond the muzzle.

The 9EZ is about 1 7/8 inches from where the front of the trigger guard goes flat to the tip of the muzzle.

Also the light needs to be powerful enough to actually be useful.

Anyone have any recommendations?

Check out the new compact Streamlights. Very well made.

Baldr Mini Laser Tactical Light 600 Lumen - Olight Store

I second with the Olight Mini Baldr recommendation. I have one on my full size M&P 9 and I’m happy with it. Small, lightweight with solid illumination and a great green laser

I have two of these. One on my .380 EZ and the other on my 9mm EZ. They are great.

If you go with the Baldr Mini, Tuxton makes a holster for the EZ with this light:
