Your lighting is what will help your cabinets look pure white . You need Led bulbs in daylight color which is 3500- 5000K range I would suggest 4000K for sure or maybe even 4500K to get your white looking white. As for the hardware I think hardware is like jewelery it needs to connect with something in the space so that could be the lighting fixtures or a stove with brass knobs and handles or some brass accessories but to just plunk brass handles on cabinets will IMO not look great.

Thanks- yes definitely a sconce over the sink as well as pendant lights over the island. It opens to the living area which will have satin brass accents. So with the bulbs would you say Pure White or White Dove?

Kfast curious what you dedicided to do? Having same debate right now
