resolved (see below)
The only options I see are "Media device (MTP)" and "Camera (PTP)", I can browse the phone files and download images from the camera directory, so the USB plug and cable are fine.
I tried following the steps on this page from Google.
I am only trying to access browser tabs (for inspect element on mobile device web development). The only software installed so far is the Samsung driver from the Samsung site and any drivers installed when the phone is plugged into the USB port.
- I have the "Developer options" enabled, and "USB debugging" is checked
- When going through the list on the page I did not install Samsung drivers first, as it is out of order on the page, so I went back into Device Manager and removed the drivers that installed from first plug in of the phone thinking this was the problem
- I then followed the steps again, installing Samsung driver first then plugging in my phone.
- After all drivers installed I rebooted (as computer told me reboot required), plugged my phone in again, and USB debugging is still not an option.

using this howtogeek link provided in the accepted answer I was able to install the Java JDK and Android SDK, which apparently is necessary to get it to work as expected and put my phone in debugging mode when plugged in
