The big S-400 missiles have ranges of 250km and 400km or thereabouts, but most cruise missiles literally cruise at medium altitudes to improve flight range so 200km from the target they might drop down and fly between 20-80m or so, but outside that range the chances of seeing them and shooting them down are quite good.
The S-350 have the added advantage of ARH so they can be below the radar horizon at launch... as long as the target is in the field of view when it starts to scan it should still get a hit.
I would suspect that for targets over the horizon the missile could transmit its radar view so the operator could select a target and perhaps launch more missiles at other targets revealed by that missiles ARH seeker.
The S-350 has the 9M100 missiles for CIWS self defence, though I agree TOR and Pantsir would also be useful too.
