IMO, it looks fine.
Preparing the surfaces (cleaning and scuffing) so the paint adheres is a BIG job. It is difficult to do properly when everything, like the trim, is installed. Get it wrong and the paint peels at the lightest bump.
The doors are doable, because they are flat. A sander will work but makes a lot of dust indoors.
If you truly cannot abide the style, I'd replace them. Get pre-primed trim and replacement doors. Paint them before installation and touch up afterwards.
Personally, I dislike single flat panel doors like those and would replace those even if I kept the trim. Use solid core doors, not hollow, they are worth the cost.
Consider replacing the doors for visual style update.
