Current State of Headless Magento

I have been out of Magento for the past year or so; what’s the current state of headless Magento? I currently have a pretty vanilla Magento 2.4.6 site, but I’d like to spice up the front end and do a rework for my customers at some point. I’ve been playing around with NextJS for a pet project, and like the developer experience with it. Are there any mature projects in this space I could use as a starting point for my store? I don’t have many customizations right now.
