Finally, but very importantly imo, what if there are 3 or more
alternatives?

Use a hash or array (depending on the selecting data).

system((zip <win32 linux other>, <cls clear nuke>)<$?OS>);
system({win32=>'cls', linux=>'clear', other=>'nuke'}<$?OS>);

Of course, this should actually be abstracted more.  What happens if
there is a fourth platform?

my %command = (
   win32 => {
       clear => 'cls',
       ls    => 'dir /b',
       dir   => 'dir',
   },
   linux => {
       clear => 'clear',
       ls    => 'ls',
       dir   => 'ls -l',
   }
);

...

system %command{$?OS}<clear>;
