How to get less Z-seam? I printed this Curvy vase from Thingiverse and it came out pretty well on my Chiron.

However, I am not happy with the Z-seam that is very large. When I look at other people's problems with this, they often seem to have too little filament at the seam, but I have too much. What setting should I change to make it less visible?

Printer: Anycubic Chiron with Marlin 2.0.7
Material: PLA
Slicer: Cura 4.8.0.
Nozzle: 0.4 mm

All Cura settings are here (except that I lowered printing temperature to 200 ºC while printing).
All files used and some pictures are here.

2021-03-07 Addendum after I made 19 test-prints of a small portion of the vase's neck. Below are some of my notes:

Combing Mode=All is better than Off
Speed=60 is worse than 40
Retract Before Outer Wall=On is worse than Off
Outer Wall Line Width 0.45 to 0.35 gave a Z-seam on the outside with more build-up
Inner Wall(s) Line Width 0.45 to 0.35. Some places has less contact between layers, so less appealing and less robust. Also less material use.
Outer Wall Wipe Distance 2.0 spread ot the seam (too much), and also made a ditch before the Z-seam (on the outside of the ring).
Coasting tripled to Vol=0.588 and Wipe Distance 5.0 is more appealing. Two changes at once make it impossible to know which one helped. 5 mm is not enough to completely wipe.
50% printing speed improved Z-seam and surface smoothness

In the future I will use slower speed for Outer Walls, test Wipe distance=2*Line Width, use Combing (turned Off because of some advice to do so when LIN_ADVANCE is used) and experiment with faster retractions and Z-movement.
Pictures and complete notes are available here.
There is a Cura option to choose a random seam alignment in the shell menu:


Z-seam alignment
This setting allows you to choose where each new layer in the Z direction starts and affects where the seam of the model will be. This is useful for models with consecutive equal layers as the seam can be visible. By changing the Z-seam alignment you can decrease the visibility of the seam. The options available are:

User-specified: Set a coordinate for the X and Y direction of the Z-seam. This coordinate is absolute by default. Example: X 100, Y 200 will move the seam to the center back of the model.
Shortest: The next layer starts at the endpoint of the previous layer. This is the fastest way of printing, but also creates the most visible seam.
Random: The next layer starts at a random point of the previous layer, which eliminates the chance of a seam. Print time will increase due to the necessary travel moves.
Sharpest corner: This puts the seam in the sharpest inward or outward corner of the model, when available. This is the best method to completely hide the seam.
