i would go with a triple for the delicious range of closely-spaced gears.

as that is not a choice here, then i'd have to go with the 2x, but switch
the rings to something like 26/38 for lower gearing. i'm too old to stand
and mash the pedals for hours at a time, don't mind coasting downhill
and enjoying the scenery.

problem i have with a 1x is the spacing between the gears. for my
riding that would suck, carrying a moderate load into the wind for
8 hours straight, or a 6-hour long uphill slog, but unable to find the
right gear.
