Application Notes or Reference Designs for 36WLCSP Packages

Hello, I was incorporating a "STM32L052T8Y6" MCU into a design. This is in a small 36WLCSP package. Are there any application notes, reference designs, or other material I could look at to get guidance or recommendations in the layout?I saw the "TN11...

I'm coding for a STM32G473MEY in mixed C and C++14. For maintainability the more I can do in C++, the better. Specifically, I want to use the bitfield<32> type in the C++ STL with enums to set my M4 registers.

I'm using the ARM-specific micro-controller compiler, not generic gcc.
