All that is really required is proper oversight - you have to have a special license and certification with training that is up to date to balance the risks. Easily feasible for professional operators, and motivated private individuals can choose to do it if they want. The danger is the general public thinking they can just treat it like they do any other car.

This is wrong and I will show you why.
Range = total energy / total consumption
Total consumption is a constant for both vehicles (lithium and sodium) - same mass
Total energy = mass of battery x gravimetric energy density
Sodium ion battery has half the energy density of the lithium-ion battery
Energy of the sodium battery = mass of battery x (half of lithium battery gravimetric energy density)
Energy of the sodium battery = 0.5 x energy of the lithium battery
therefore
Range of the sodium vehicle = (0.5 x energy of the lithium battery) / total consumption (which is constant as we said) = 0.5 x range of lithium vehicle
There is something else you have not considered which is that in order to keep a large lithium battery operational it need to expend energy to heat itself and cool itself to the correct temperature, which a sodium battery doesn't need to. This is a major loss factor in current lithium based EVs. So in fact the sodium vehicle will have more than half the range of the lithium for the same weight, with the difference being more marked the further the ambient temperature is away from the optimal temperature for the lithium battery.

I don’t think the problem is hydrogen engines, more like the fuel cell.

The fuel cell is the engine.
The problem is the fuel itself. Hydrogen atoms are the smallest atoms therefore they will leak out of any container made of a material made of larger atoms. To really make it safe you'd need to keep it in a box with lead walls 30cm or more thick, which massively increases the weight of the vehicle you're trying to propel.
In open air or for a short period of time (like a day) it's not a very serious problem. But in an enclosed space, left for a week, dangerous concentrations of hydrogen are going to build up around the vehicle which can explode.
There's also the issue that if you leave your car in a car park for 2 weeks to go on holiday all the hydrogen will leak out while you're away so you can't start it when you get back (as many people used to have problems with dead lead-acid batteries)

Agreed.
And yes that's precisely the problem. Preventing leaks is essentially impossible, and it's highly explosive so unregulated vehicles that could park in underground car parks for a couple of days + spark = no more apartment block

"It doesn't rely on rare earths"
It relies on petrochemicals of which there are limited amounts, and certainly the amount you can burn is very limited if you don't want big environmental problems later.
There are solutions. Hydrogen fuel cells have great energy density, although operating needs care. Better for buses, trucks and taxis where the driver can be properly trained to deal with the dangers of leaks.
You can use sodium batteries which are extremely cheap, extremely safe, operate in environments you can't use petrol in let alone lithium. The only drawback is they have about half the energy density of lithium batteries. But for something so cheap who cares if you can only get half the range? Plenty of people will buy that

OK. I don't really know all that much about it, I'm just an amateur not a coder.
It seems there are 2 different things: hacking the events by producing a new event with an existing event id, forcing the relay to have to decide which is the real one or "updating" its record of which one is authoritative, and explicitly saying "this is a new event (with a different event id) that references and obsoletes this other event" which is a protocol level thing that has to be explicitly coded

Even though you have a basement I would still run the floor heating element through the ground floor, I think it will be tricky otherwise.
I am a bit jealous since here we have only air to air heat pumps, standard for Mediterranean because mostly used for cooling rather than heating but much less energy efficient than ground to ground.
It's good to diversify though and have a number of different solutions that can overlap instead of putting all your eggs in one basket, even if any one solution doesn't provide 100% coverage of your total needs.

You should be able to do this pretty easily and it will be very energy efficient and free to run but will probably only raise the interior temperature by an 80:20 type ratio of what you feel comfortable with so you'll want to top it up with the wood burner occasionally as well. Think of the ground heat pump as "baseload".
