Isn't doing physics in a mathematically rigorous way very hard or close to impossible? I think Quantum Field Theory and the Standard Model remain non-rigorous because of their dependence on path integrals.

Yes, doing QFT rigorously is hard because of path integrals. It's possible to do QM rigorously, as the "rigged Hilbert spaces" formalism suffices.

  Ballentine's book is a modern textbook that relies on that (as opposed to Shankar which you mentioned)

    Nice, thank you, this was exactly the kind of resource I was looking for :)
