You basically want to take a Postel's law type position, where you're quick to accept others' feedback and make the changes they request, while being conservative in the feedback and requests for changes you emit. Keep in mind that you're trying to get stuff done, not win debates with developers, who can be unbelievably persnickety and shortsighted.
If a reviewer asks you to change something and you believe your version is just as good as what they suggest, change it. If they suggest something they claim is "totally optional", do it. Remember, we're getting stuff done. This is faster than arguing (over stupid shit that isn't going to matter anyway).
On the other side, if you ask for something in a review and they're not gonna do it, bias toward letting that slide unless it's a real problem. If you think a piece of feedback will seem embarrassing, mention it in a private chat or something first so they have an opportunity to address it.
Code-style issues should not come up in reviews. Set up a linter, fail builds on lint errors, and forget about it.
Maybe it is difficult for introverts, but you know, a lot of things are going to be difficult. Sorry about it.
