> VoLTE will work over 5G

Doesn't 5G use VoNR? Or does VoNR imply the same SIP call format, but just over 5G instead of 4G?

My understanding is that VoLTE/VoNR/VoWiFi is all the same 3G era IMS stack (with updates since then) and thus SIP over IP over either GPRS Tunnel Protocol over low level radio interface or WiFi
That is my understanding of VoNR, but unfortunately I don't have experience with it.
