Abstract
We report first measurements of branching fractions, $CP$-violating charge-asymmetries, and polarizations in various charmless $B$ decays at Belle II. We use a data sample of electron-positron collisions collected in 2019--2020 at the $\Upsilon$(4S) resonance from the SuperKEKB collider. The data sample corresponds to an integrated luminosity of 34.6 fb$^{-1}$. All results are consistent with known values. In addition, these results provide extensive validations of the detector performance and analysis strategies.
