For UPC you will need an UPC cable TV connection. Does your apartment/house have one cable TV connection, and is it provided by UPC?

Swisscom and init7 are both either through the good old telephone line using DSL or, if available, Fiber to the Home (FTTH).

Cable TV and DSL might come with additional basic connection fees which results in a higher monthly costs than advertised. In case of cable TV this might be sneakingly hidden in your auxiliary bill. You can get rid of the cable TV connection fee if you do not use the cable TV socket for TV, Radio, or Internet and get the socket sealed by the cable TV company. Be sure how much you actually pay and how you can get rid of hidden fees for things you do not use.

If you have FTTH I would go with that as it is symmetric (same upload and download speed). Provider? If you just need bare internet and it has to be fast init7 seams to be quite good.
