The possibility of doing precision measurements at hadron colliders has attracted lots of interest over the last few years. Among other processes, diboson production stands out as a way to probe EW and Higgs dynamics and constraint indirectly New Physics. This kind of process is already being studied at LHC, despite being handicapped by the need of using decay channels with high uncertainties. In this talk, I'll show how the higher luminosity and center of mass energy of the future FCC-hh collider will allow us to probe processes with cleaner but rare final states that are unaccessible at the LHC. More specifically, I will focus on the diphoton leptonic decay channels of the Wh and Zh production processes. I will discuss our study of these channels at the FCC-hh in the SMEFT framework and how doubly differential distributions can be used to gain even better sensitivity to certain higher-dimensional EFT operators. I will also compare our projections with those for future lepton colliders to emphasize their complementarity.
