It looks fine, it's basically the same thing I had before I decided to add some step-down corners to reduce the number of loops going through the whole mesh. The topology of flat surfaces doesn't really matter much, so as long as you can sufficiently buffer the edges, anything goes, however having too many loops can make the mesh too busy to look at and annoying to edit. If you don't want to be pedantic about keeping quads, add extra support loops and preview the subdivision result until you stop getting distortions, a few n-gons would've been fine here.

You don't often need bevels on subdivision surfaces, if you want a sharper edge just push the support loops in closer or add a second loop. One of the key points of subd is being able to quickly remove or change loops as you develop your design, and chamfers tend to hurt that.
If you want to model with chamfers, that's a viable alternative too, and it would've been suitable for this subject, you just have to start with more edges for rounded objects since they won't smooth. Pic related is how much smoothing you can get out of the bare minimum of chamfers, it's just 2k tris and probably all you need if it's just some small detail in your scene.
