How can I negotiate a senior PM promotion, salary, remote work, and bonuses?

[Grace.G]

I'm up for a promotion to senior project manager at my tech firm, and the HR conversation about the new salary and responsibilities is scheduled for next week. I've researched market rates and know my value, but I'm terrible at negotiation strategies and always end up accepting the first offer out of discomfort. I need practical advice on how to structure the conversation, when to introduce my counter-offer, and how to handle potential pushback on things like remote work flexibility or bonus structure without damaging the relationship.
