How to improve at floating point datapath design

I just started a career in "numerical element design"/"floating point datapath design" and I am having a hard time gathering technical knowledge that goes past the "widely known basic implementations" from papers/existing RTL within my company.

I am talking about leading-edge tech node implementations, multi-GHz fmax, low power, super optimized while crazy complicated.

Do you know of any type of resources that could cover this? Thanks
