Looking for advice on YVR-Europe May '25

I'm starting to research YVR to central Europe for next May likely in paid J, possibly with some Avion or Aeroplan points thrown in. Destination could be LHR, FRA, MUC, AMS, CDG, MXP.

Prefer AC or *A, but could look at others. Also prefer non-stop.

I don't have any recent experience with these routes. Any advice on best comfort and likely best price?

Many thanks.
