につき / をめぐる / に関わって

The topic is something being argued or fought over.

Noun をめぐる Noun vs Noun につき: Use をめぐる. It implies a contest around the topic (遺産をめぐる争い), which is why it turns up with disputes and debates. につき is the flat administrative 'regarding' or 'per' of notices, with no conflict implied.

Stating a connection to a matter, without claiming any dispute.

～に関わって vs Noun をめぐる Noun: に関わって marks involvement in or connection with something. をめぐる specifically frames the topic as contested, so using it for a plain association overstates the case.
