  text: We theoretically investigate the stationary properties of a spin-1/2 impurity
    immersed in a one-dimensional confined Bose gas. In particular, we consider coherently
    coupled spin states with an external field, where only one spin component interacts
    with the bath, enabling light dressing of the impurity and spin-dependent bath-impurity
    interactions. Through detailed comparisons with ab-initio many-body simulations,
    we demonstrate that the composite system is accurately described by a simplified
    effective Hamiltonian. The latter builds upon previously developed effective potential
    approaches in the absence of light dressing. It can be used to extract the impurity
    energy, residue, effective mass, and anharmonicity induced by the phononic dressing.
    Light-dressing is shown to increase the polaron residue, undressing the impurity
    from phononic excitations because of strong spin coupling. For strong repulsions,
    previously shown to trigger dynamical Bose polaron decay (a phenomenon called
    temporal orthogonality catastrophe), it is explained that strong light-dressing
    stabilizes a repulsive polaron-dressed state. Our results establish the effective
    Hamiltonian framework as a powerful tool for exploring strongly interacting polaronic
    systems and corroborating forthcoming experimental realizations.
