interesting points all! yes. i was trying to figure out what it was that bothered me about those scenes with the other stormtroopers, and you have put my finger on it. also it was weird to me that they would be able to so easily disable Lupito Nyongo's character, who I would assume be able to use the Force to some extent because of her outfit? and then also not kill her, but leave her in a trash compactor -- when she was clearly several ranks above stormtrooper AND Finn had a personal grudge against her. like, "oh yup killing the Red Shirts is fine but we want to reuse her in later films so we'll just disable her wink wink."

my partner had an interesting take on the hug at the end. Finn was wounded and being carried off the ship and onto transport and everyone was making a big deal over him (everyone) and carrying him off. they left Rey standing on her own. admittedly maybe some of them didn't know that she had been involved in the fighting, or what her role was with Emo Darth? but my partner saw the hug as Feminist Leia sees Young Woman Fighter Get Ignored for Wounded Dude, and hugs her.

(although also maybe because she can sense the Force, she senses the Force in her, idk.)
