When I first found the fediverse, I setup my site using #Indieweb principles, thoroughly enjoying the use of sematic html and attributes to describe the data. It made so much sense!
IndieKit was something I tried early on that may interest you - it uses the POSSE (Publish On Site, Syndicate Elsewhere) concept, with syndication available to microblogs using static site generators like 11ty, along with social media posts to mastodon and bluesky.
