Final negotiation for finance manager offer: data-backed equity and bonus

[KevinT]

I'm a senior financial analyst with five years of experience at a large corporation, and I've been offered a new role as a finance manager at a mid-sized tech company. The base salary offer is competitive, but I believe the bonus structure and equity package are below market for the increased responsibility. I'm preparing for the final negotiation call next week. For other finance professionals who've successfully navigated this, what specific data points and benchmarks are most persuasive when discussing total compensation beyond just base salary? How do you effectively articulate the value of your analytical skills and past cost-saving initiatives in monetary terms? Is it better to negotiate each component separately or present a total package target, and what are reasonable asks for sign-on bonuses or accelerated equity vesting in this market?
