Your list has brought a bit smile to me, my dear. I promise more wolfy-shenanigans to come soon.
As for #4 - the MC's agency and action being cruelly taken is serving as part of a building drama in the background. Some play their MCs as capable and take-charge, but the way this is working out for MC here is that they can't be that even if they want. This tension may lead an MC come apart in some way). But not to worry, we are building up to something good and your MC isn't going down without a fight.
For #5 - the mark will not influence MC's magical capabilities. It will add some flavor later in the story but overall it's mainly the physical appearance of the mark that is effected by your choice.
#6 - MC will make a trip home soon. For MCs that already wield weapons, they'll be able to hone what they have in their arsenal. For those who do not typically have weapons, they'll get a chance to learn one and take it with them.
#7 - no worries! I'm happy to answer as long as there's no spoilers. ^_^
