Abstract: The investigation of B-meson decays into charmed and charmless hadronic final states is a keystone of the Belle II program. It offers theoretically reliable and experimentally precise constraints on CKM unitarity, it is sensitive to effects from non-SM physics, and it furthers knowledge about uncharted b->c hadronic transitions. Recent results on branching ratios and direct CP-violating asymmetries of B->K,pi decays are presented that lead to world-leading tests of the SM based on the isospin sum rule. First observations of new D->D(*),K,Ks decays and new results from combined analyses of Belle and Belle II data to determine the CKM angle phi3 (or gamma) are also presented.
