Can I change the site icon?

or will it always show a “home” icon?

site.yml

title: My Title
icon: play

You can change it via the panel.menu option: panel | Kirby CMS

    'panel' => [
	    'menu' => [
		    'site' => [
			    'label' => 'Overview',
			    'icon' => 'cog',
		    ],
		    'languages',
		    'system',
                    // other entries
	    ]
    ],

Note that you then need to list all other default entries you want to have in the sidebar menu.
