I am planning to put two adjacent outdoor duplex outlets on an Edison

am wondering which is the best way to do this, both from the NEC point
of view and from a convenience point of view.

The three options I see a

1. Two separate GFCI outlets -- the cheapest solution, AFAICS.

2. Two separate GFCI breakers.

3. Ganged GFCI breakers (separate breakers with a handle tie -- if
available for Cutler-Hammer CH)

4. 2-pole GFCI breaker -- probably the most expensive solution.

Have I missed any? Which would be best?

Both #2 and #3 sound impossible (with a shared neutral). There would
be no way to connect the neutral properly. You would be unable to use
more than 1 outlet at a time.

I think #1 is best.

Ayup, with a shared neutral, there's no way to use a GFCI breaker
because the GFCI works by comparing hot and neutral current. You need
GFCI outlets installed after the point at which the two circuits diverge.
