PE hard products is very undifferentiated with hardly any stand-out seats.
I would toss SK into the mix. Connector flight books into their C/Y+ cabin so meal (not worth it) plus full free bar. At CPH you're given lounge access.
Suppose it hasn't emerged in your search as a) not sure if it connects from ZRH and b) it isn't a daily flight.
Edit: checking your dates it yields a CHF 1900 cost however can be had as low as CHF 1430 from my very quick search.
