I've got the Fenix 6 Pro and loading a GPX on is pretty straightforward. It'll show the route on the map and then beep or buzz when I'm approaching a turn so I don't miss it.
Forerunner 945 is basically the Fenix 6 Pro series in its triathlon variant
Forerunner 955 is Fenix 7
Epix is posh Fenix with AMOLED screen
(things like Forerunner 745 does breadcrumb trails, but not overlaid on a map)
seems like 'routable mapping' is the term for Garmin
