Best outdoor deck railing for short-term rental vs. resale vs. aesthetics

[Ian Jeffreys]

We are renovating a home in the Catskills and stuck on what railing to install on our outdoor deck—cable or metal.  We plan to use the home for short-term rentals—so safety is important.  We might sell if the rental market doesn't pan out—so curb appeal is important.  The home is fully surrounded by woods—no neighbors in sight; so views are important.  There is a deck around most of the house that is 8-10' above the ground in the front, and a full story above the ground in the back.  
I've attached photos with rough mockups of the options (A, B, & C) we are considering.  We would be so grateful for any input, experience, or recommendations from homeowners or agents regarding what would be the preferred choice for 1) attracting rental guests in the short term, 2) retaining value for resale and not looking dated in 10 years, 3) protecting ourselves from accidents.  

Thank you in advance!  Ian
