use statments are executed at compile time, even if you define them inside the body of a function.

In order to load Net::SSH2 or when not available, Net::OpenSSH::Compat::SSH2, this code should work: 

BEGIN {
  eval {
      require Net::SSH2;
      1
  } or eval {
      require Net::OpenSSH::Compat::SSH2;
      Net::OpenSSH::Compat::SSH2->import(':supplant');
      1;
  } or die "unable to load any SSH module";
  Net::SSH2->import();
}

Though, you would be better using Net::SSH::Any that takes care of doing all this conditional loading for you and provides a better API. It is still a work in progress, but basic functionality like running commands remotely and capturing the output already works fine.

update: the full script fixed: 

use strict;
use warnings;
use Data::Dumper;

my %connection_details = ( host => 'localhost', @ARGV);
my $SFTP = SFTP_connection(%connection_details);
print "SFTP: ", Dumper($SFTP), "\n";
exit (0);

BEGIN {
    eval {
        require Net::SSH2;
        warn "Net::SSH2 loaded";
        1;
    } or eval {
        require Net::OpenSSH::Compat::SSH2;
        Net::OpenSSH::Compat::SSH2->import(':supplant');
        warn "Net::SSH2 supplanted";
        1;
    } or die "unable to load any SSH module: $@";
    Net::SSH2->import();
}


sub SFTP_connection {
    my (%connection_info) = @_;

    ## Connect to the sFTP server
    my $SFTP = Net::SSH2->new();

    $SFTP->connect($connection_info{'host'},22)
        or die "Unable to connect to the remote sFTP server \n\n $@";

    ## Login to sFTP server
    $SFTP->auth_password($connection_info{'user'},$connection_info{'pa
+ss'})
        or die "Unable to login Check username and password. \n\n $@\n
+";

    return $SFTP;
}
