I think a LAN-connected machine would be good, if you could use an app or open-source, well-documented API to control the machine, but there is no reason a washing machine should need to connect to the outer internet. You can VPN into your local network if it's that necessary to control it away from home.
An SOC is a bad idea for laptops in my opinion, it just makes it harder to repair and less modular. I understand that it helps to compact the device, but it should only be used in phones if at all.
