For a flip:
I know it is not about he money, but there is no need to toss money away either.
I wouldn't be concerned about the cables. Whatever is cheapest. You won't get an extra nickel for DA cables.
For tires, I wouldn't worry about avoiding wire bead, since having a folding tire is only meaningful for a spare or a severe weight weenie. Again, zero return on investment if it cost any extra.
Also, even though I like Kool Stop pads, I wouldn't waste money by putting them on a flip bike. Just like the cables, it is unlikely to get you any return on your investment beyond any other pad.
For any of the above (except the tires, if more expensive) the extra few dollars may be worth it for personal use.
