Abstract	The investigation of B-meson decays to charmed and charmless hadronic final states is a keystone of the Belle II program. Analyses of such decays provide reliable and experimentally precise constraints on the CKM Unitarity Triangle fit, are sensitive to effects from non-SM physics, and further knowledge about uncharted b->c hadronic transitions. We present recent results on branching ratios and direct CP-violating asymmetries of several B decays, which result in a competitive SM test based on the Kpi isospin sum rule and first observations of three new B->D(*)KKS decays. We also present new results from combined analyses of Belle and Belle II data to determine the CKM angle phi3 (or gamma).
