The Standard Model Effective Field Theory (SMEFT) framework provides a powerful approach to identify, correlate, and interpret deviations from the SM in particle physics experiments while minimizing model assumptions. In this talk I present recent progress in global SMEFT analyses of Higgs, top quark, and electroweak production data and on its (automated) matching to UV complete scenarios. I also discuss quantitative projections for the sensitivity of future particle colliders such as the FCC-ee on the parameter space of the the SMEFT and representative UV models. I motivate the need to carefully disentangle QCD effects, such as those related to proton structure, when performing EFT fits to LHC data, and demonstrate the usefulness of ML algorithms to boost the sensitivity of EFT analyses.
