Self-amalgamating tape may be waterproof amalgamated to itself, but
will it stick watertightly to PVC sheathing to prevent moisture
creeping in?

Yes. It is basically an adhesive tape with a propensity to dissolve
itself and bond into a solid mass when stretched slightly. It will stick
to PVC sheath, PE sheath and miscellaneous metals.

I think some form of adhesive would be required for certainty

The tape already has an adhesive on one side.
