I recently discovered the Syntax web development podcast, hosted by Wes Bos and Scott Tolinski, and I've sinced started binging on the episodes at 1.25x speed! The podcast covers a wide range of full stack web development topics with usually one area per episode. Both Wes and Scott run successful coding tutorial businesses and are experienced developers. The episodes are packed full of tips, tricks, links, sick picks and the odd shameless plug for both of their excellent course offerings. A recent episode on design systems was interesting because they do a great job of giving you an overview and directions on where to start on the topic.
