There are a large number of “string vacua” which contain particles and interactions with the quantum numbers and symmetries we call the standard model, but (1) they typically contain a lot of other stuff that we haven’t seen (2) the real test is whether the constants (e.g. masses and couplings) are the same as observed, and these are hard to calculate (but it’s improving).
