Fireplace Design Help, Please

I’m entering the final stretch of a grueling reno, and have to make a decision on what to do with 3 fireplace “hearths” on the parlor level…the stone area where the fireplace spills into the room. One will be wood burning, the others will not be used.

I’m thinking carrera for one that will stay non functioning, but unsure whether to tile or go with a stone slab for the others.

My floors are 4 in pine (original subfloor) in a natural finish, surrounds/mantles are marble.

Anyone have some pics of what they’ve done or links for inspiration?
