A lot depends on the room size, light and your personal style, but if in doubt then pull from patterned fabrics that include your colour, so for example, depending on the teal you have the attached suggests you could pull in navy blues, lighter blue/greens and greens, creams and whites and some warmer pops of a pinky red. Use that fabric as an accent (a cushion, a chair etc) and pull in other fabrics with texture or pattern for interest for soft furnishings.
Personally I would always stick to white for bedding, particularly with such a strong bed colour but then add a bedspread or throw and cushions for interest. I think it's classier than patterned bedding and also allows you to style it up easier.
Personally I hate most white wardrobes or wardrobes which stick out visually, it screams utility in a room you want to be calming. Mine are painted the same as our bedroom wall colour to try and make them disappear visually a little bit, they're floor to ceiling (an IKEA Pax hack which makes them look built in) and if they were white they would definitely bring the room in and make it feel smaller.
