Hi Boomer,
As someone said, a lot depends on personal taste but as you see from Niki's photo, kitchen unit doors don't have to have complicated mouldings.
FWIW I would suggest:-
a) Familiarise yourself with the so called 'Euro hinge' they don't show & are quite easy to fit (My guess is that's what Niki used)
b) Choose some nice handles that you booth like (You'll probably have noted how the handles Niki choose help to improve the 'look')
c) Use MDF (It doesn't 'move' and can be painted, choose a colour that matches your appliances and floor / walls if possible))
d) If you really want a 'frame & panel' look add the frame around the panel as suggested by Adam. Use your router to get a nice shape and use that style throughout all the doors. I would suggest you pass on the raised panel idea at this stage.
Good luck
