I follow a few sites but can’t filter Lemmy by domain or follow domains, so I want to create a community where a bot reposts my RSS feed to surface the most interesting items from those sources. Which Lemmy instances or communities are bot-friendly, have signups enabled, and permit this kind of mass automated posting?
You could run your own.
Running an RSS reader is probably a lot easier though.

Strays a bit from what you asked so ignored if not welcomed, but in case it helps, or in case there's a way to have microblogging posts appear on Lemmy:
Sending RSS feeds to bots such as @birb or @owner should give a bot profile to follow a given feed's updates. And both should be usable from pretty much any Mastodon instances, making the potential usable instances much broader. Two small things to note however, first the Studio Rafflesia's bot's usage rules are in Japanese so potential language barrier there, and second and confirmed by the author, sending a feed to RSS Parrot through Mbin doesn't work.
Other than that, and in line with the question, I second !meta.
