At least for the first part of your question, I guess it's because PPI, which Perl::Critic uses internally, no longer recognizes the code as a sub and so those policies don't apply.

use warnings;
use strict;
use PPI;
use PPI::Dumper;

my $Document = PPI::Document->new(\<<'END');
use Function::Parameters;
use Types::Standard qw( Num );

fun foo (Num $x) {
    $x + 1
}
END

my $Dumper = PPI::Dumper->new( $Document );
$Dumper->print;

__END__

PPI::Document
  PPI::Statement::Include
    PPI::Token::Word      'use'
    PPI::Token::Whitespace      ' '
    PPI::Token::Word      'Function::Parameters'
    PPI::Token::Structure      ';'
  PPI::Token::Whitespace      '\n'
  PPI::Statement::Include
    PPI::Token::Word      'use'
    PPI::Token::Whitespace      ' '
    PPI::Token::Word      'Types::Standard'
    PPI::Token::Whitespace      ' '
    PPI::Token::QuoteLike::Words      'qw( Num )'
    PPI::Token::Structure      ';'
  PPI::Token::Whitespace      '\n'
  PPI::Token::Whitespace      '\n'
  PPI::Statement
    PPI::Token::Word      'fun'
    PPI::Token::Whitespace      ' '
    PPI::Token::Word      'foo'
    PPI::Token::Whitespace      ' '
    PPI::Structure::List      ( ... )
      PPI::Statement::Expression
        PPI::Token::Word      'Num'
        PPI::Token::Whitespace      ' '
        PPI::Token::Symbol      '$x'
    PPI::Token::Whitespace      ' '
    PPI::Structure::Block      { ... }
      PPI::Token::Whitespace      '\n'
      PPI::Token::Whitespace      '    '
      PPI::Statement
        PPI::Token::Symbol      '$x'
        PPI::Token::Whitespace      ' '
        PPI::Token::Operator      '+'
        PPI::Token::Whitespace      ' '
        PPI::Token::Number      '1'
      PPI::Token::Whitespace      '\n'
  PPI::Token::Whitespace      '\n'

For the second part, I can confirm the same behavior, but I can't say in which of the modules this is a bug...
