We present our continuum extrapolated lattice QCD results for the cross-correlators of baryon number, electric charge and strangeness, and compare them to calculations from the Hadron Resonance Gas (HRG) model with the most up-to-date hadronic spectrum. We analyze the contributions to these observables from hadronic correlations and self-correlations, and their relation to experimentally measurable quantities. We study the dependence of the cross-correlators on the kinematic cuts, and suggest novel observables to allow for a model-independent comparison to experimental results. We perform the direct comparison to available experimental results, for observables related to net-$\Lambda$ and net-kaon fluctuations.
