Cura Profile for Ender 3 V2 with 0.8mm Nozzle

Edit: This issue has a $20 bounty for resolving the issues in printing at a 0.6mm layer height.

I am trying to print very large items that do not require a lot of detail on the Z-axis. Because of this, I have an Ender 3 V2 (4.2.2) running Marlin 2.0 setup with a 0.8mm nozzle. I have seen a lot of information that printing up to 0.6mm heights should be fine with the nozzle however in testing some more challenging pieces of a larger print, I have discovered that I get some pretty unsightly issues at anything over 0.4mm layer height.

The main issues I have are.
1. Anything over 0.4mm layer height produces blobs on most of the Z seam.
2. Anything over 0.4mm layer height produces inward bowing of the walls at tight corners.
3. Even with a 0.4mm layer height, there is still some blobs on the Z seam at the tops and bottom of print walls.

I have attached both a Cura profile of the 0.56mm layer height I have been trying to get work and the Cura project file of the example. If you have experience with this, please let me know what I am doing wrong.

Thank you!
