The mixing of ->pack and ->grid only applies within ONE parent, different parents can have different geometry managers within one application. No Problem. I do it all the time. Example follows. 

#!/usr/bin/perl

use strict; # https://perlmonks.org/?node_id=11136705
use warnings;
use Tk;
use Tk::Pane;

my $mw = MainWindow->new();
$mw->geometry("+0+0");
$mw->maxsize(1000,1200);
$mw->minsize(400,300);

my $scroll = $mw->Scrolled('Pane',
                         -scrollbars => 'osoe',
                         -sticky => 'news',
  )->pack(-expand => 1, -fill => 'both');

my $f = $scroll->Frame->pack(-expand => 1, -fill => 'both');

foreach my $row (0..10)
  {
  foreach my $col (0..12)
    {
    $f->Entry(
      -text => "rc $row $col",
      -width => 0,
      )->grid(-row => $row, -column => $col, -sticky => 'news');
    $row or $f->gridColumnconfigure($col, -weight => 1);
    }
  $f->gridRowconfigure($row, -weight => 1);
  }

# example of ->pack in a different Frame

my $buttonbar = $mw->Frame(-bg => 'blue',
  )->pack(-fill => 'x');
$buttonbar->Button(-text => 'Exit', -command => sub{$mw->destroy},
  )->pack(-side => 'right', -fill => 'x', -expand => 1);
$buttonbar->Button(-text => ' Another Noop',
  )->pack(-side => 'right', -fill => 'x', -expand => 1);
$buttonbar->Button(-text => 'Noop',
  )->pack(-side => 'right', -fill => 'x', -expand => 1);

MainLoop;
-M $0 < 0 and exec $0; # FIXME for testing

Applications resizing themselves without user input is a BAD IDEA. Just imagine your user trying to click on something and having it move out of the way just before the click. BAD IDEA!

See the "widget" demo program for an example of what an HList looks like. It should have come with the Perl/Tk package.
