I went with the silver because I have already has the Honda SS Braided throttle and clutch cables along with the Spiegler SS braided brake lines. If you change one, then you’ll want to change all of them. I think the silver/braided looks better for what it’s worth.
several colors can go either way, but the matte i would think that black would be best. There really isnt much that is shiny on the bike. BUT ... if you were to go with a contrasting color, it could really set the bike off. Going with the red pinstripe in the wheels, you can go with a red cable. If you wanted to get really creative you can change the pinstripe to something like an orange, and go with orange cables ... or even blue, green .... but i would think that the silver or stainless would be my last choice.
