Hidden-charm pentaquark-like $P_{\psi s}^{\Lambda }{\left(4459\right)}^0$ and $P_{\psi s}^{\Lambda }\left(4338\right)$ resonances are studied in a constituent quark model as molecular meson-baryon structures. Such states are found in the $J^P\left(I\right)={\frac{1}{2}}^{-}\left(0\right)$ channel with masses and widths compatible with the experimental measurements in a coupled-channels calculation with all the parameters constrained from previous studies. Other candidates are explored in the $J^P={\frac{1}{2}}^{-}$, ${\frac{3}{2}}^{-}$ and ${\frac{5}{2}}^{-}$ channels in the charm and bottom sectors, with isospins 0 ($P_{\psi s}^{\Lambda }$ and $P_{\Upsilon s}^{\Lambda }$) and 1 ($P_{\psi s}^{\Sigma }$ and $P_{\Upsilon s}^{\Sigma }$). Additionally, the formalism is extended to study the $P_{\psi ss}^N$ ($P_{\Upsilon ss}^N$) pentaquarks, where eight candidates are predicted as ${\overline{D}}_s{\Xi }_c$ molecules in $I=\frac{1}{2}$, with $J^P={\frac{1}{2}}^{-}$, ${\frac{3}{2}}^{-}$ and ${\frac{5}{2}}^{-}$ for the charm sector and nine candidates as $B_s{\Xi }_b$ for the bottom one.
