When you get to Process > Noise Reduction > Reduce Noise, usually a preset isn't the answer, but some manual fiddling.
Here's the way I approach this:
1. When I set the noise print, I play/loop the clip and note the level of the noise in your meters. When I get to the threshold in the noise reduction window, that level will be the extreme highest threshold I use, only going lower from there.
2. When it comes to the reduction, I check the Noise only box while I'm setting it, and boost the reduction until I'm getting noise, but not too much signal I want to preserve. If I hear voice in there, I'm doing too much. And I rarely end up going beyond 60%.
3. Uncheck the noise only box, and listen to the signal with noise reduced to fine tune further.
Remember this is noise reduction, not noise elimination. And, the STP tool is pretty good for what it is, but it's not anywhere near the best out there.
Good luck, and I hope this helps!
