So with the filament being dry (and the LIDAR cleaned and the filament calibrated) you can look at the settings.
While not having printed PETG-CF yet, I have resolved similar surface issues by printing slowly with different fan speeds and additional top surface layers to effectively cover over these types of top surface defects.
However, there are now better solutions here in the forum. Try settings from here or, more for the CF loaded PETG, here.
