There are many possibilities, the one I use on my CV is Text+icon:
I used to work in an online gaming company with games on touchscreen terminals and watching people playing, if you don't indicate that there is a place where you can access to a link, a very large percentage will never touch it, even if it is a big red blinking button.
The standard is the underlined blue text, but depends the environment may not be very noticeable. The same with the icon. Both things together leave less doubt.
The most understandable icon to click on a map or place, besides the one from Google Maps, is:
I understand your boss.
One of the biggest mistakes we (all the designers) have, is to think that our work is for millennials or people who perfectly knows the use of apps, websites and computers. But the reality is that there are many people who don't even know that a PDF can have links.
