> I just saw an article suggesting to use 4096 instead:

In fact, it's a change in the Linux kernel directly proposed by Eric Dumazet (Google) for Linux kernel 5.5:
https://lore.kernel.org/netdev/20191030163620.140387-1-edumazet@google.com/

The change has already been merged upstream:

/* Maximum queue length specifiable by listen.  */
#define SOMAXCONN	4096
