I used this one https://divinityoriginalsin2.wiki.fextralife.com/Walkthrough
It covers all side quests (at least i didn't found a quest that wasn't in the walkthrough) so you will unlock pretty much all trophies.
The only thing is to make a cloud/usb save before the fight on the boat after leaving Fort Joy to do both trophies about Dalis' minions, another one before speaking to the Doctor in Arx to be able to kill him / reload / make the pact, and a finale one just after le last fight of the game of the game in order to unlock all endings.
If you want to minimise playthrough, i recommend making an honour mode game playing Fane as a main (for the covenant trophy) and taking at least one companion (for the chosen trophy).
And just a little warning on online coop : some trophies don't unlock if you are not the host of the game, i can think of a few one like "Toy story" "Puritan's walk" "Cat person" and there may be others as i already had trophies from the first 2 isles when we started an online game.
