Oh wow, are in luck! These kinds of communities have been building up over the last few years (maybe decade or so?), and now they're quite prevalent. I was about to share a few links (like indieweb.org, fediring.net, etc.)...but, then remembered stumbling upon the following blogroll/link page that does a wonderful job of capturing some really good starting points: https://shellsharks.com/indieweb

Enjoy! :-)
