Fediverse

I'm dealing with some health issues at the moment, and it's getting exhausting to update everybody one by one, so I'm looking for some ideas of where to host a blog in a way that might give my friends & family a small, painfree introduction to the fediverse, or at least something that's more on the FOSS side of things. A family friend used caringbridge.org a few years ago, which looks like a not so terrible fallback option, but I figured I'd see what else is out there before making a decision. The last time I really did much blogging was probably 20 years ago on livejournal, so I'm pretty out of touch with the current options.
