The higher domestic voltage also allows for more powerful appliances. A typical French (and I assume most of EU, perhaps Asia) home receptacle circuit can supply 3.8kW, compared to 2.4kW in the US, so over 50% more. Plug connected space heaters and flatirons are typically 2kW, rather than the usual 1.2kw or 1.5kW in the US. An EV "granny cord" connected to a household or garage wall receptacle delivers 2.3kW. A Dacia Spring will charge in ~11 hours at that rate, so it's practical. You can also use ligher wire (less copper, lower cost) for the circuit wiring, and for the appliance cables. And for a given size, there's less loss (waste heat, inefficiency) from wiring resistance. I'm sure that there must be good reasons that the US chose 120 volts and most of the rest of the world chose 240 volts, but I don't know what they are.
