Best Way To Resolve Messy Boolean Operations? (Shading Artifacts)

Hi there.
I’ve been doing some modelling for a couple of years, and like many, I’ve found the saviour that is the Boolean modifier.
However, it sometimes just leads to some messy mesh in topology flow and normals no matter what I do.
My issue is the shading artefacts that arise when you try to connect the “booleaned” part back to the original. I can get rid of most of the artefacts with but, it just isn’t as clean as I’d want it.

My current general solution:

The artifacts it still makes:

Why don’t you use sharp edges, looks like that would be the solution for your example (in conjunction with edge split modifier). By the way, I suspect that your bevel modifier will not work with this topology.

Sharp edges worked wonders!
Also, the bevel does work. Just had to set it to absolute to get the nice edge-reflections
