For my first play-through, I like to play lawful good because there's a lot of conflict there, and also because I generally prefer to see justice prevail in a story.
FR is a points-of-light setting where civilization is separated by vast expanses of wilderness and tribalism. BG3 captures this well with the Tieflings harrowing journey from Elturel to Baldur's Gate. (Why don't they take common river route??) So anyway, how does a LG paladin behave in this wild space? The laws and customs of civilization basically extend only 5'.
I see the druid trader Arron support casting the refugees out into the wilderness because there's not enough to go around, and then his inventory is full of resources. Customs dictate fair trade, but concern for the innocent tells me he's a greedy hoarder that could do with some selective trimming. Can't say exactly what I'll do, but I'll hmm and hrr over things like this that don't seem right.
Basically, I play as if my MC has to face judgment himself at the end and must show an overwhelming pattern of justice and altruism.
And I'll do the same for following play-through; decide on a particular moral outlook, e.g. CN or LE, and work out a consistent pattern of behaviour.
