I think you summed it up well. Cantrips being the only spells you can't pick up later, I tend to value these rather highly as long as you can think of broad-level uses for those you pick up. The skills in question are also all one-off type skills (you know it or don't). I think these should be shared across the party, and they don't seem worth having expertise in to me. I think it really comes down to the style of your DM when it comes to skill checks, and how often you think those extra cantrips will benefit you.Regarding a dip in Cleric, what is everyone's thoughts about the Arcana domain?
