In a full transient, is D,,ACC really any better than applied displacements (which are known to produce sprurious results at the beginning of a load step)? Doesn’t the program just convert the accelerations to displacements?

Yes, D,,ACC is better as it uses the Newmark assumptions directly to insert the appropriate displacement boundary condition into the solution so that accelerations remain smooth.
