ASA top finish quality

I have been testing my 3d model in many different filaments, and based on specs and for my use, ASA should be the way to go.
I am building a device/phone holder for a suction cup. It will be used inside a vehicle, on a sunny day and needs to be strong enough and not to deform at these temperatures.

When I print my model using PLA for example, I get the perfect finish, precision, everything.
But with ASA and ASA-CF, that top layer is not great.
I have tried with different top finishes, and with and without ironing. It is ok, but not great.

I will upload how prints with a few different options are looking.
The white one is PLA (all filaments are from Bambu, printed on X1-C)
Loos perfect, and have a Hilbert Curve top surface pattern. I can’t use it because PLA is not temperature-resistant enough, but it is a control print.

We have one more print with the same settings, just a different filament preset, and top surface looks smudget. (Bottom left on the picture)

There is one more print just with a normal monotonic top pattern (top left), but it has a different look inside and on the edges.

Two on the right are with ironing, but sometimes it looks ok, and sometimes not, it is not consistent.

Also sharing my slicer settings.

Can I get some advice or guidance, on how to make top finish better with ASA? Or suggestion for some other filament (I have purchased many of them and tested them, but not have ideal results yet).
