The Sony A7 III is the camera I own and the one I recommend to everyone. Coming from the Sony RX1 II I miss the 42mb but I have to say that the combination of amazing sensor and lenses makes the A7 III the right choice for enthusiasts like me. You can spend more and get the R version, but if most of your photos are to be shared online save the money and with that buy lens.
