I also second the chain crossbodies made for the outlets. I use them at the airport. They come with a crossbody strap and wrist strap (and I add a keyring to turn mine into a shoulder bag). Inside there's a deep pocket that fits an iphone7 in case (I think same size as the 10) and 10 card slots. It won't fit a large bunch of keys though. I think the Marlow or Marley is the boutique version.

I also love this wristlet from the legacy collection. I put my credit cards loose in the turnlock pocket and my phone, chapstick, in zip pocket. Cannot be turned into a crossbody but easy to find on eBay just search
Coach turnlock wristlet or Coach legacy wristlet.

Here's one I don't recommend. It's the new dreamer wristlet. I hoped to fit my phone in the front pocket and could not. It didn't actually fit as much as the wristlet above but was much larger. Very pretty but not functional for me :/

I think the Noa currently on Coach's website would work for you too:
