What is a good unused Windows outgoing port for a client?

I need to set up an outgoing port for a client app.
But I don't know if it uses tcp or udp or even ipv4 or ipv6.

Googling, I found these four commands which gave these results shown below.
https://learn.microsoft.com/en-us/troubleshoot/windows-server/networking/default-dynamic-port-range-tcpip-chang

From those results, how would you advise I set the arbitrary outgoing port?

netsh int ipv4 show dynamicport tcp

Protocol tcp Dynamic Port Range
---------------------------------
Start Port      : 1024
Number of Ports : 64511


netsh int ipv4 show dynamicport udp

Protocol udp Dynamic Port Range
---------------------------------
Start Port      : 49152
Number of Ports : 16384

netsh int ipv6 show dynamicport tcp

Protocol tcp Dynamic Port Range
---------------------------------
Start Port      : 1024
Number of Ports : 64511


netsh int ipv6 show dynamicport udp

Protocol udp Dynamic Port Range
---------------------------------
Start Port      : 49152
Number of Ports : 16384
