Bevel inside extruded geometry the right way?

[qwertzdergaertner]

How can I bevel this inward extrusion, without getting too sharp polygons or ngons? Ending up with clean typology and nice smooth shading?

Would really apreciate some feedback!

use the Smooth by Angle & Bevel modifiers:

When you use ARC as Miter Inner option you’ll get ngons.
To fix you need a destructive workflow applying the modifier.

Also, it worth watching this BlenderBob very little video (read also the comments).
