      abstract     = {Excited-state contamination remains one of the leading
                      sources of systematic uncertainty in the precise
                      determination of hadron structure observables from lattice
                      QCD. In this letter, we present a general argument, inspired
                      by meson dominance ideas and implemented through the
                      variational method, to identify which excited states are
                      enhanced by the choice of the inserted current and
                      kinematics. The argument is supported by numerical evidence
                      across multiple hadronic channels and provides both a
                      conceptual understanding and practical guidance to account
                      for excited-state effects in hadron three-point function
