In 2 wire vs 3 wire I sometimes choose 4 wire.
In 2 wire for approximate temperature a 10k PTC is not too bad.
In the old days gas gauges in cars used 90 ohm 2 wire.
They interfaced well with those clever magnetic gauges and they stayed at the same reading when you turned off the engine.
But nobody likes interfacing 90 ohm senders to a microcontroller.
Many things in cars today run off 3 wire pots running on regulated 5V.
This is a much more convenient signal to interface.
I had a propane tank that used a 90 ohm two wire.
I didn't feel like pulsing the current and measuring so I put in an I2C 3D (only 2D used) magnetic sensor, i.e. 4 wire.
