^^^^ Yep.

If you can, measure the steerer tube of the existing fork - from the fork crown to the top of the tube under the cap. You can do it on the bike. The stock new length for many sus forks is about 255mm or so. Some hybrids (my Scott for example) have a head tube which is longer than MTB's and will need a 300mm steerer tube cut down a little. You may need to search for a longer 300mm steerer tube if you're over 252mm on the Cannondale.

If you're ok on length, a short travel road suspension fork is an easy swap. 1 1/8th", 700c, unthreaded, with brake bosses to suit. You may need a new star nut. Check the tube diameter of the current fork to make sure it is 1 1/8th unthreaded. (Duh!)

SunTour forks worked well on my last urban bike. The short travel forks are tuned for road use, so even without a lockout there's little pedal - bob or brake dive.

A cheaper fix though, could be a taller/fatter front tyre like a Schwalbe Marathon.

Is that an option?
