      abstract     = {We study a non-universal flavor scenario at the level of
                      the Standard Model Effective Field Theory, according to
                      which the matrix of Wilson coefficients $c_{uW}$ of an
                      up-type electroweak quark dipole operator is aligned with
                      the up-type Yukawa coupling. Such an alignment usually
                      follows from the assumption of Minimal Flavor Violation
                      (MFV), away from which we step by allowing the entries of
                      $c_{uW}$ to be sizable along the first quark generations. A
                      particular example, which we refer to as ``inverse hierarchy
                      MFV', features Wilson coefficients inversely proportional to
                      quark masses, and arises from BSM models respecting MFV and
                      containing heavy fields that replicate the mass hierarchy of
                      SM quarks. We then analyze the phenomenology driven by
                      $c_{uW}$ at colliders and at lower-energy flavor
                      experiments. We show that precision measurements of the
                      process $pp\rightarrow W h\rightarrow \gamma\gamma\ell\nu$
                      at FCC-$hh$ could set an upper bound on
                      $|c_{uW}|\lesssim\mathcal{O}(10^{-2})(\Lambda/{\rm
                      TeV})^{2}$, with $\Lambda$ the cutoff of the effective field
                      theory. This bound is an order of magnitude stronger than
                      the existing LHC bounds. Moreover, we estimate that $W
                      h\rightarrow b\bar b \ell\nu$ at HL-LHC could also give
                      competitive bounds. In the low-energy regime, we consider
                      bounds arising from rare kaon decays, which turn out to be
                      loose, $|c_{uW}^{11}|<\mathcal{O}(1)(\Lambda/{\rm
                      TeV})^{2}$. We finally demonstrate that our flavor and
                      operator assumptions can be derived from a weakly-coupled UV
                      model, which we choose to simultaneously illustrate the UV
                      origin of inverse hierarchy MFV.},
