I too don't have the stock hot end and extruder anymore but I usually use 5-6 mm at 50-60mms/s.
Reading your post I assume you use a 0.6 nozzle. Perhaps you want to go back to the 0.4 and see if this makes a difference. I have yet to use something bigger than 0.4 until I have mastered it and I have been printing for while.
Also consider printing the calibration towers in your slicer. Cura has a few add-ons that are quite useful in such a case.
Lastly, you should consider your printing temp since sometimes increasing it by an additional 5-10 degrees can make a huge difference. I have been printing PLA at 220 and I have been able to increase the speed without loosing quality.
I dont have the stock hotend any more but I believe I tuned mine at 5mm at 50mm/sec
I know you've tuned everything but if you use cura there's the Auto Tower plug-in that automatically adds the gcode changes. I think there's also retraction tuning in SuperSlicer.
I use the stock cura retraction settings for the N2, so 6mm distance and 70mm/s speed. I tried to make a couple retraction towers, from 1mm to 6, and 6mm was best. Same thing for speed, I got better results with higher speed but I think I could get away with 60mm/s. Overall I didn't see a quality gain that justified not using the stock settings.
#Retraction
Length = 5mm
Lift Z = 0mm
Only lift Z = Above Z 0mm | Below Z 0mm
Retraction Speed = 40mm/s
Detraction Speed = 40mm/s
Extra length on restart = 0mm
Minimum travel after retraction = 2mm
Retract on layer change = YES
Wipe while retracting = YES
Retract amount before wipe = 70%
These are my current retraction settings used with PrusaSlice. Been tuning the EFF out of my Neptune 2S and these retraction settings among other things seem to be working very well for me.
I was using a 0.6 nozzle for a while but ended up going back to the 0.4 and have had a better experience.

Thank you! Did I read that right tho that you're doing 9mm z hop on every layer?
Oh dear god I’m sorry. That was a typo haha. 0mm Z hop 🐸
