Include NRST on your debug connector.

Provide a UART for diagnostic output; also some "uncommitted" IOs ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

... with at least some testpoint / pad for debugging via GPIO & scope.
