Coast Fire? How am I doing; when can I hit Costco?

Just looking for some perspective and opinions on my options and when I can coast: details below

46yo - ~1.3m NW - MCOL - mortgage free ~550-600k home value. Single family it’s 2kids 50% of time

401k ~600k (maxing yearly)

Taxable brokerage - 70k (investing 25k yearly)

Liquid cash - 130k (recent large bonus, will pump into Brokerage over time)

529 - 175k (2 children)

Expenses: ~3k - 4k monthly

Just looking on feedback on if/when I can pull the plug, what I am not considering, perspective, feedback etc.

Ideally, would like to pull the plug ASAP on the corporate grind, sling hotdogs at Costco and let the 401k grow to 67 before tapping any of it and SS
