I don't know what Revere Pewter would look like with the browns you have, but I've seen pictures of it with walnut and calacatta marble and it look very nice. Buy a sample and paint a board with several coats and set it in the room to see if you like it. It is a Benjamin Moore color.

If it were me, I would paint it. SW Greek Villa? It’s a nice warm/creamy white. If you do white it will blend with the walls, which may be a good thing, but the stained glass will stand out more. A dark color can also be good because dark colors usually recede. Get a plan together before you start painting things. You want your rooms to have flow. Think about your moulding, stair railing, etc. and all your fixed surfaces (flooring, countertops, tile, anything that doesn’t move). You want it all to work together. Look at photos and start putting together mood boards with your finishes and your furnishings.

Black, brown, or green would go well with your warm brick color. It's hard to see the roof, but I think it is brown? I had a house with similar color brick, and the trim was painted SW Urbane Bronze; it looked good with some off-white for the smaller details. You should also consider a new color for your front door.
