Analog or digital sensors?
In any case, build a input filter (RC, LC, etc...) that have tuned bandwidth to match max. data rate/frequency. This with some SW filtering should be enough.
Twisted pair is cheap, easy and well working. Screened twisted cable is even better. Smaller the loop, the better. Small loops reduce common to normal mode conversion of external interferences (i.e ESD fields). And no piggy tails...
It might be a good idea to add ESD protection also to sensor end(s).
And some good luck is always needed even you might be a pro
