Quartz countertops are very popular right now. With white cabinets and a grey floor, I think one of the below options would be beautiful. Best of luck!

Quartz is a manufactured product and can be very attractive. The manufacturing process allows a much wider range of colors than you’ll find in natural stones such as marble or granite. The appearance of the finished engineered stone is rich, even luxurious. The finish has a depth that can’t be produced with solid surface materials like Corian.

Quartz has the same durability as concrete and granite, but is quite a bit more forgiving, so it won’t chip or crack as easily. It doesn’t have the same hardness in the feel that some people find unpleasant.

Like other hard surface countertop materials, quartz is non-porous so it resists staining much better than granite, marble and concrete. It stands up to juice, oil, wine, tomato, coffee and other sources of stains in the kitchen. For cleanliness, a non-porous surface means that it will not harbor bacteria or viruses. You can always be confident that you are getting your quartz countertop absolutely clean, and that’s a great benefit in both the kitchen and the bathroom.

I have quartz and love it; there are quartz patterns that look more like marble than ever, including ones in cream/brown tones that might work well with your kitchen. Lusso comes to mind as having golden undertones, though there are many other beautiful choices.

Based on the age and type of cabinets I would not spend the money for quartz. Look at the new formicas that are on the market now

Concrete is a great option.

I like quartz as well but agree that you could get by with a less expensive product if the rest of the kitchen is not being renovated.
