A few options:

1.) One is to anticipate a possible pedal strike obstacle and adjust your pedaling stroke to avoid it.
2.) Buy a FS bike with the highest BB you can find.
3.) Buy some shorter crankers.

My latest bike purchase I went with option 2 (345mm BB Height) because my previous bike had a lower BB and pedal strikes would occur often. On my newest bike it's now rare that I have a pedal strike anymore. I can't count exactly 2 in the last 3 years.

Make sure your rebound settings are correct. Slow rebound means your bike stays lower to the ground longer. Faster rebound get's you back up higher. Just don't overdo it, otherwise it will feel like the bike is trying to buck you off. If you can't make the problem go away your best solution will be shorter cranks.
