  We study the correlation function between one single-trace scalar operator
and a circular Wilson loop in the $4d$ $\mathcal{N}=2$ superconformal field
theory with gauge group $SU(N)$ and matter transforming in the symmetric and
anti-symmetric representations. By exploiting supersymmetric localization, we
resum the perturbative expansion of this correlator in the large-$N$ 't Hooft
limit. Furthermore, using both analytical and numerical techniques, we provide
a prediction for the leading term of its strong coupling expansion and we
compare this prediction to numerical Pad\'e resummations of the perturbative
series.
