Like others have said, the FX3/A7SIII is an incredible powerhouse. I upgraded from the A6500 and I can say confidently that it is a big and welcomed upgrade - from the 4K capabilities to 10 bit to longer battery life and beautiful colour science when shooting in S-Log 3. The FX30 could also be a great fit if you still plan on using your APSC lenses, and it's an incredible camera too, If you're comfortable shooting at lower ISO's and not fully vested in photo capabilities, it's a solid choice!
