Neje 3 Plus with their 12W plus laser head.
I cut slowly with 40% of the power and make 3 pass. The cutting is even better than what you see because I stupidly glued the photo paper to another more rigid paper.
So it is too thick.

I'm having a hard time finding some PVC sheets with the right size (A4 or paper), inkjet printable, not adhesive and around 0.3mm thick.
I found some but minimum order is 1000 pieces so I'll pass.
