Most cars have that feature list, as for the things you dont want, you can just toggle them off or not use them.
Though sedans are a dying breed, so I'd get one sooner rather than later. Everyone and their brother wants SUVs/CUVs and sedan offerings are getting slimer by the month.
If you're not using the feature, then a bug in it would be hard to manifest.
And as for the more complicated hardware, I am afraid that ship has sailed.
Cars have become incredibly complex in the last couple of decades. They are covered in sensors and filled with computers to handle everything, from the injection of fuel and shifting to acceleration and braking to infotainment and climate control.
If you want Cruise Control with distance following that means you get brake-by-wire and accelerator-by-wire with a computer making decisions about when to do both.
You cannot eat your cake and have it too.
If you want a simpler car, then look to the 90's - they still had computers, but obviously the technology was more limited. You won't get radar cruise control or much in the way of blutooth though, obviously. You can still have an automatic sedan with pretty good safety. (Not as good as modern, but decent)
