Choosing a car with this need list is simple and down to common sense imo
If such high end spec/list as mentioned is needed that in itself makes things easy to boil down in fact just by needing Ventilated front seats must boil it down to a few cars
You say
( Spec essentials are:
Heated Front Seats – Both adults have spine issues now, heating the back really does help.
Ventilated front seats – In the summer there’s nothing worse that the burning of sitting on dark seats that have been in the sun for hours.
Heated steering wheel – My hands can suffer in the cold, I find my grip weakens, this will help
Electric Tailgate – With 2x bad backs not having to reach and pull down what can be a heavy tailgate is a massive boost
Electric driver’s seat – if it automatically gives me more space to get in/out or simply makes adjusting the seat easier, I’ll take it
Electric Passenger’s seat – again, if it helps the Mrs then happy wife and all that.
HUD – I’m a fan of keeping eyes on the road, this just helps out massively
Apple CarPlay – I do tend to become annoyed at commercial radio stations, even more so at what Radio 2 has become so I listen to my own playlists now. This has 3 options, Wired, Wireless and none.

As far as choosing your own car it seems a simple task thats being made out to be complicated although I appreciate you like a spreadsheet
As the required mentioned spec can only apply to a few available scheme cars thus reducing the choice to just a few motorbility cars and not as complex as its being made out to be and a few test drives later job done
Takes a little longer imo if your needs are few as you then have more available cars to try and choose from
Cant beat a good youtube review imo followed by a few showroom visits.
Just my take on it and each to their own
