On the sim, if your plane is autolanding capable, it's only captain discretion if to use it or not. the ILS of FS (but of other sims too) is always CAT III (unless the loc signal is offset, like on some runways) and the rules on a sim are dictated by the sim's owner.
Autolanding is a useful option in real planes and a pleasant thing to do, from time to time, on the sim. But at times is useful, or even necessary even on the simulators. Personally I am proud to be a SIHL (Stick In Hand Lander), but can't help but remember that time I was landing on fumes with a Bae146 in the airport of Bangkok with no visibility at all. Did not have autoland. Did not have a HUD. Did not have visibility. Did not have even fuel to divert on another airport.
Barged on the runway at full landing speed. The visibility was so low I couldn't see the runway lights even when on ground. Never seen such a low visibility before or since in FS. Luckily the gear did not crash even touching ground with me not flaring, and to reach he gate I could use the ATC assistance. It could have ended worse.

No matter how dearly we love SIH landings, sometimes autolanding is a good thing to have, even on a simulator.
