• I had partial success only with the hubzilla wp plugin: can cross-post from hubzilla to my blog, but not in the other direction..
• I've been thinking that instead of using hubzilla's articles module, it would also be possible to use a hubzilla category like "blog" in order to create custom category pages, which one could probably include, for example, on the profile page. It's possible to use the summaries tag in ordinary status posts, though not a custom name for appearance in permalinks.
• indeweb.org has a slew of tools and plugins that enable one to convert an ordinary blog into a 2-way system for communicating with a part of the fediverse. So theoretically, it would possible to simply use one's blog and not establish a separate presence on a social network. I have experimented with these and so far didn't manage to connect to my website from hubzilla. I was trying with the "bridgy" system.
• I usually aim for simplicity; using one tool for a number of different uses, even at the expense of using crude hacks. But I may end up continuing to use my blog's wp installation alongside hubzilla. The presentation of articles looks better on the blog, whereas hubzilla does the networking thing better. Clever people or those with lots of time on their hands can often get nicer results and indieweb.org website has a couple of nice examples, but my own solutions generally don't look quite as elegant.
