Yes. But trim is often a more durable finish- sometimes semi-gloss. Although you don't have to paint trim a different finish than walls if you are OK with touch-ups and like the matte look more than semi gloss or gloss.
To keep a room looking 'quiet' it's wise to minimize the paint colours and textures and use your accessories to create the colour and interest.
Hope this helps.

Benjamin Moore has altered cloud white over the years. It used to be a very soft white (yellow tint) and now I think is a bit less, but still a warm white vs a cold white (blue tint).

The best way to determine the white you wish to use is to test a few samples in the room, on the walls (paste over the cabinets) and view the few options at all different times of day and evening.

Every designer uses at least 3-5 testers to ensure they love the final colour that is selected and then painted.

Hope this helps!

Thank you!
