How much equity should I ask?

I'm considering an offer from a BLR based startup which is >Series D. This is for a Growth role.

Currently in a Series B startup where I have been for about 3 years now (been here since inception) and have 1% equity. What would be the right % of equity to ask for while making the switch? 9 YOE.

Would also be helpful if anyone can share the benchmarking of % equity for maybe every Series for the larger benefit of the community. TIA.
