Can you give me insulation suggestions for a Northeast coastal home?

I have a 1920s beach house directly on the ocean, in a flood plane & exposed to strong winds. We are in the Northeast, zone 5. The house is currently unheated and lacks full insulation. We plan to insulate top to bottom when we renovate the house this year. The house is unheated and has only been partially insulated upstairs. We are now undertaking renovations: shingling, rewiring, and installing new windows throughout. The perfect time to insulate. Upstairs we will replace the wallboard and fiberglass batt on the exterior walls. Downstairs we have thick wooden beadboard walls nailed to studs with no insulation so insulation needs to be pumped through a hole. We may heat in the future and will need to place the HVAC system in the attic (also uninsulated)bc of the flood plane. Batt and cellulose might create mold and mildew problems. Closed cell soy-based spray foam seems like the most practical option. However, I'm concerned by numerous reports that it emits toxic off-gas

Ellen,

Based on your location and the potential for water infiltration into the walls, I would not recommend installing batt or cellulose within the wall cavities.

Also with that said the approach...
