In this work, the sensitivity of future germanium-based reactor neutrinoexperiments to the weak mixing angle $\sin^{2}\theta_{W}$, and to the presenceof new light vector bosons is investigated. By taking into account keyexperimental features with their uncertainties and the application of adata-driven and state-of-the-art reactor antineutrino spectrum, the impact ofdetection threshold and experimental exposure is assessed in detail for anexperiment relying on germanium semiconductor detectors. With the establishedanalysis framework, the precision on the Weinberg angle, and capability ofprobing the parameter space of a universally coupled mediator model, as well asa U(1)$_{\rm B-L}$-symmetric model are quantified. Our investigation finds thenext-generation of germanium-based reactor neutrino experiments in good shapeto determine the Weinberg angle $\sin^{2}\theta_{W}$ with $<10$\% precisionusing the low-energetic neutrino channel of CE$\nu$NS. In addition, the currentlimits on new light vector bosons determined by reactor experiments can belowered by about an order of magnitude via the combination of both CE$\nu$NSand E$\nu$eS. Consequently, our findings provide strong phenomenologicalsupport for future experimental endeavours close to a reactor site.
