to be honest if your budget can stretch to the ionic 5 ultimate, that is the most fully loaded car on the scheme in my opionion. if you have another 900 you can add the tech pack that features Remote Smart Park Assist (RSPA), Parking Collision Avoidance (PCA), Automatic flush door handles, driver seat position memory function and relaxation seats on both driver and passenger seats. if range is more you thing and its not to low the ionic 6 premium is the right one to go, its only second to telsla globally for efficency.
the nissan in evolve trim is pretty much fully loaded, but even advance trim is good.. there are some good options on cars at the moment but the price is steep. the ionic 5 ultimate does have a lot though and the cooling seats really do help in the summer (i dont have one a friend does) i have tried the ev6 and loved the power, but a 8 month old demo with 6k on it should not be rattling (noises) like it was so it was 100% crossed off.
