Sorry, did not do the Sunnegga Funicular. But the intercity trains arrive right at Zermatt centre. As far as I understand it's not really a big place to walk around (people carrying skis everywhere during winter to the various lifts = can't be that bad...) which again I can't really help as I travelled only on the Gornergrat up and down to Riffelberg as I stayed on mountain and only came down at the end of ski day to adjust boot fitting as I stupidly bought a new pair of boots that required adjustment after each ski day

before rushing back up on the last train.
But if you can spare the time, the view from Matterhorn Glacier is amazing via a different funicular; The view also at the end of the Gornergrat is equally amazing. Fingers crossed on good weather days.
