Hi PP, and welcome to MySwissAlps,
1. There will be daylight from 8 AM to 4:30 PM. Fog can certainly occur in December, even all day long, but it might as well be sunny all day. You won't know for sure until about a day before. As for the temperature: most likely it will be freezing at night but not during the day. But that's an average. It can be much warmer or colder.
2. A boat trip on Lake Zurich or Lake Lucerne is an option, except when there's fog. There are plenty of museums in Lucerne and Zurich, e.g. the Transport Museum. And in Winterthur too: www.winterthur-tourismus.ch/en/Erlebn isse/Kultur/Museen. There will be various Christmas markets (Lucerne from December 3, and at least two will be open in Zurich). More activity tips can be found on the Zurich and Lucerne page.
3. Absolutely. Any time is a good time. You just need to be lucky with the weather and make plans accordingly. Hiking in the mountains won't be possible indeed, but there are a lot of other things you can do.
