kilowatt hours ARE more intuitive than watt seconds when talking about something like solar panels, electric cars, and household energy where generation and consumption are better understood on the scale of hours.
No they're not. You're just used to them.
Are you seriously trying to say that if you're talking about a solar panel it makes more sense to talk about how much energy it produces per second than per hour. If you wanted to think about the amount a panel can produce per day are you sitting there thinking about how many seconds of sunlight it will get in a day.
If you want to estimate the energy usage of a 400 watt lighting system during an 8 hour workday you think it's more intuitive to go 400 * 3600 * 8 / 1,000,000 than 400 / 1000 * 8?
The reason seemingly every electrical utility in the world uses kWh is because hours are the more intuitive unit of time for this context.
