The MAC address you have chosen is LAA (0x12). No idea how it impacts the workflow, but you can try changing it to UAA. Your screenshots suggest that W5500 does not even try to connect to the server, however it depends on where you have Wireshark listening to traffic. ARP is broadcast, while SYN is unicast, and if you listen on another device than W5500 and server you may not see targeted traffic.
