Abstract: We report on recent measurements of $B$ meson decays to hadronic final states using electron-positron collisions at the $\Upsilon(4S)$ resonance collected from 2019 to 2022 by the Belle~II experiment and corresponding to an integrated luminosity of 362 ${\rm fb^{-1}}$. We present new results to determine the quark-mixing parameter $\gamma$, performed combining Belle~II data with the full Belle data set, and analyses of two-body decays relevant for the determination of $\alpha$. We also present recent results on branching ratios and direct {\it CP}-violating asymmetries of several $B$ decays, which result in a competitive standard-model test based on the $K\pi$ isospin sum rule and first observations of three new $B \rightarrow D^{(*)} K K_S^0$ decays.
