The Unsullied are a different matter. They are trained to just follow the orders of whoever has paid for their services. I don’t know where the show would go with their mindset at this point.
I see two options for the unsullied and it all depends on greyworm I think.
He will either start to see Danny as the person she has become the same as the original masters that enslaved them and once Jon (I'm 95% sure it will be him kills her) will take over command of the unsullied and take them back to slavers bay to keep it free or where was Missandei from wasn't she talking about how it had no protection? That would be a good ending for them.
Alternatively He stays in fog of grief and blindness to Danny's flaws to In which case They go in a rampage when she dies and I think Drogon might have to be the key to taking them out, although I'm not a big fan or Drogon switching alliances from danny to Jon who else could take out that army? Or it's always an option Danny doesn't die and they stay helping her keep power possibly being used to help her continue to conquer other lands. But I think it's unlikely she lives after last week.
Agree I would love brienne to end up head of the kings/queens guard.
For me I want Danny dead taken out by Jon to be honest if Jon, Danny and Drogon could go in one tragically sad incident that would be great!
I would like to Arya take a step towards becoming a person again not just an assassin. Although if she wants to take Drogon down first I'm ok with that.
I want a big moment for Tyrion don't mind what just big and fitting.
Ideally I'd still like it to end in a democracy I know I probably won't with Sansa, Davos, Sam, Tormund (I know he want but I want him to) maybe gendry And tyrion if he lives forming a council/government. I don't think that will be what happens I don't really care who ends up on the throne. If I had a vote it would be ghost! Give him an ending he deserves 
Brann 😴😴😴 can become a tree or whatever.
Bronn I'd like his storyline to have meaning this season but I can't see how it can do he can just stay away!
I doubt that's what will happen it's probably to close to a happy ending for thrones but that's what I'd like!
