When I go to Garmin coach, it only gives me the option of 5K, 10K or half marathon?
Should I use a third party app to import a plan instead?
or did I just buy the wrong watch if I want to get coached on a marathon plan?

You can use the self-guided plan for marathon (there are six of them, even for Instinct 3, at https://connect.garmin.com/modern/training-plan?tab=FindAPlan - as shown on the screenshot below) , you can use a 3rd party plan, or you can exchange Instinct 3 for a watch supporting the adaptive Garmin Run Coach Training Plans (listed at What Is the Garmin Run Coach Training Plan? | Garmin Customer Support)
