Thanks for the feedback. I based that diagram on the MultiPlus-II 2x 120V manual (as it was suggested here earlier). That model shows "Load connection AC out1 - From left to right: N (neutral), L2 (phase 2), PE (earth/ground), L1 (phase 1)". So I think it's accurate if I use that model. It also has an AC Out2 which is simply passthrough (not inverted) but short of a separate sub-panel I struggled to figure out how or why to use that in the setup I diagrammed.
I'll think more about the comment about the outlets. On my boat the only outlets that would have an active load on them (if shore was removed) would be the salon stereo, which would only be in standby, and the toothbrush charger in the head (but that would be charged). We don't leave any other AC items on when we're away (the refrigerator is AC/DC). But thinking about it, we don't need the salon stereo on the inverter at all - we use the flybridge stereo when anchored. I'll move that to the other side.
Thanks,

I looked at the Multiplus info. It appears that they offer connections to do the buss-splitting (inverter/non-inverter circuits) inside the unit. You can do it that way, or not, at your choice. Personally I would do it as shown in your diagram (and not inside the inverter).
Another point: The inverter does have 2 x 120V outputs, but only outputs on one of these when inverting (as I interpret the tech data).
