Set your extrusion multiplier to .88 and .2 layer heights, 235C temps. 95C build plate. In simplify 3d reset to factory FlashForge Creator Pro defaults then change the settings I listed. 20% infill should be good. Don't change anything else for now. Try to get that to work then tweak here and there to dial things in.

As mentioned before .2 layers are all that is really ever needed for general parts. Perfect your prints at .2, then try .1 layers.

Inland filament is very good. I generally do a calibration cube for each filament to see if the settings I generally use is good to go. But I don't dwell over calibration cubes. I have had perfect calibration cubes printed but in real world printing it was still over extruding. So I turn down the multiplier untill things smooth out. .88-.9 is a good range for extrusion multiplier to start with.
