IMO, the new information doesn't make a lot of difference. Perhaps...
- After the auction, ♠K = 10, ♦Q = 8, ♥ = 6.
- After learning about possible Canapé, ♦Q = 10, ♠K = 8, ♥ = 4.
That doesn't seem right. If declarer is certain to have five hearts and may only have four clubs, so that the heart fit is likely to be 5-3, there is less urgency to set up fast winners; if declarer is certain to have at least five clubs and may only have four hearts, so that the heart fit is likely to be 4-4, there is more urgency to set up fast winners.
Thus, I would be more inclined to lead a diamond against the auction "without canapé" and a spade against the auction "with canapé". I might lead a trump against the "without canapé" auction, while I would never do so against the "with canapé" auction (that lead would seem to me bizarre, since it is the lead most likely to allow a 4-3 fit to make).
Probably, though, I would lead a spade against either auction. It isn't clear to me at the moment how we're going to beat this contract anyway, but I know how we're going to let it make: by leading a diamond and finding declarer with
♦Ax, dummy with
♦K10 and others, and our side with two fast spade tricks that have just become one slow spade trick to go with our heart trick and our club trick.
Of course, declarer could have
♠Ax and dummy
♠Jxx(+), while declarer also has
♦Ax facing a bunch of low ones and we have enough control to prevent declarer establishing his clubs to pitch dummy's spade losers in time (now do you see why it matters how many clubs declarer surely has?) But that's life.
