I have 4 doors and 4 drawer fronts that have a recessed panel with trim molding on the inside of the stile and rails.
I don't know what the name of the style is, I'm sure it has one, but anyway the frames have a small rounded corner that the trim will go around.
I started with the appropriate sized circles, routed the outsides, then cut 2 pieces out of each circle. That way I could get diagonal grain for each corner. The rest are pictures that pretty much show the process I'm using.
I'm also making the rest of the straight trim pieces. Rout the edge, cut off to width, rinse and repeat.
I see a lot of tedious hand sanding detail work in my near future.
