Yes SMRs look very promising and I believe NuScale has one commercial plant in the early stages of production but it won't even be finished until the end of the decade[1].
The optimal mix using today's technology seems like it would be traditional fission for baseload combined with (solar/wind + battery) / hydro for variable / peak grid load.
