I know that usually the number of indices on a tensor indicates it’s rank, so how do you represent a scalar/rank zero tensor. I’ve had trouble making this work and it seems at times like there’s ambiguity between scalars and vectors.

          You're right: the number of indices indicates the rank, so a scalar has no indices and hence a single component (cf. $n$ components of a vector).
