Alright, so I got what I wanted! Since I was using jQuery tabs on my page, I attached a click event to one of my tab links that loads the map. Now, it will only load the map when someone clicks that particular link/tab (which I’m okay with). So, on tab click, render map and resize to 100% width and height. Thank you @acf-support James for leading my in the right direction!

Here is my updated code:

<script type="text/javascript">
    (function($) {
    
    function render_map( $el ) {
    
        // var
        var $markers = $el.find('.marker');
    
        // vars
        var args = {
            zoom		: 16,
            center		: new google.maps.LatLng(0, 0),
            mapTypeId	: google.maps.MapTypeId.ROADMAP
        };
    
        // create map	        	
        var map = new google.maps.Map( $el[0], args);
    
        // add a markers reference
        map.markers = [];
    
        // add markers
        $markers.each(function(){
    
            add_marker( $(this), map );
    
        });
    
        // center map
        center_map( map );
		
		google.maps.event.addListenerOnce(map, 'idle', function(){
			 google.maps.event.trigger(map, 'resize');
			 center_map(map);
		 });
		 
    
    }
    
	
    function add_marker( $marker, map ) {
    
        // var
        var latlng = new google.maps.LatLng( $marker.attr('data-lat'), $marker.attr('data-lng') );
    
        // create marker
        var marker = new google.maps.Marker({
            position	: latlng,
            map			: map
        });
    
        // add to array
        map.markers.push( marker );
    
        // if marker contains HTML, add it to an infoWindow
        if( $marker.html() )
        {
            // create info window
            var infowindow = new google.maps.InfoWindow({
                content		: $marker.html()
            });
    
            // show info window when marker is clicked
            google.maps.event.addListener(marker, 'click', function() {
    
                infowindow.open( map, marker );
    
            });
        }
    
    }
    
    function center_map( map ) {
    
        // vars
        var bounds = new google.maps.LatLngBounds();
    
        // loop through all markers and create bounds
        $.each( map.markers, function( i, marker ){
    
            var latlng = new google.maps.LatLng( marker.position.lat(), marker.position.lng() );
    
            bounds.extend( latlng );
    
        });
    
        // only 1 marker?
        if( map.markers.length == 1 )
        {
            // set center of map
            map.setCenter( bounds.getCenter() );
            map.setZoom( 16 );
        }
        else
        {
            // fit to bounds
            map.fitBounds( bounds );
        }
    
    }
    
    $(document).ready(function(){
        
		$( ".mapclick" ).one( "click", function() {
			//$('.mapclick').click(function(event) {			
          	$('.acf-map').each(function(){
				render_map( $(this) );
			});			
			
			$(window).resize(function() {
				$('.acf-map').height($(window).height() - 170);
			});
				
			$(window).trigger('resize');	
		});

		//$height = $('#wrapper').height();
    	//$('.acf-map').height($height);
		
    
    });
	
    })(jQuery);
    </script>
