Fusion
Please export the design as a .f3z. I receive an error message when downloading and opening it:
The curvature map shows some problem areas:
And the Isocurve analysis shows a isocurve orientation I would not expect to see:
Was this created natively in Fusion?
Have you tried thickening this before applying fillets?

I can try adding fillets after thickening
Yep, I figured out by now that this wasn't created entirely in Fusion 360. At least one of the surfaces is a 5-degree NURBS surface and most "normal" CAD systems cannot create 5-degree surfaces.
The screenshot is from ZW3D. Its thickening tool is less temperamental Fusions but I was also not able to thicken the object there:
Some of the corner surfaces i pointed put in my previous post look like they were created withe the patch tool in Fusion. Is that a correct assessment ?
Whenever a 4-sided opening is to fill, use a loft, not a patch. Imagine the (boundary) patch to work like a stiff tablecloth that you stretch over a welded frame. The Isocurve analysis shows that the UV coordinates of the surface don't align with the boundaries and that means the surface quality approaching the boundaries is less than ideal.
This corner surface shows this clearly.
The surfaces to the left and right of the corner also look less than ideal
