I'm not sure that any particular flavor of serial is the right answer,
but I do think wired is the way to go. I have never understood why
Ethernet isn't the obvious answer. Perhaps I'm missing something.

Because ethernet is also more expensive than a simple serial bus. Ethernet
requires an ethernet chip which is more expensive than a RS-485 or CAN
driver, a transformer and last but not least, a huge amount of code in a
processor just to be able to handle ethernet traffic, compared to what is
needed to do the sensors' job.
