There are very few WordPress plugins for building a TRADITIONAL community/discussion forums (as opposed to the Q&A site, support site, social network, etc) — WForo, Asgaros, Simple:Press… and MAYBE bbPress (which, in my view is best suited for providing customer support, as it lacks many basic features you’d expect from a traditional forum software).
And NONE of these has the sub-category/sub-group feature you desire.
That said, I’m really wondering if you’ve thought through the distinction between a CATEGORY/GROUP vs FORUM, and concluded you indeed want your hierarchy at the category level?
All forum software I’ve ever tested (and I’ve tested a bunch, including OGs like vBulletin, phpBB, myBB, XenForo, etc) that have hierarchical categories/groups make it clear that categories/groups are ONLY meant for visual grouping of forums only. The actual forum posts/topics belong to a FORUM (and its parent forum). Posts do not go into a CATEGORY/GROUP at all.
And that means (at least for the WordPress plugins), these CATEGORIES/GROUPS are not clickable (no URL for them), and it’s impossible to navigate to them beyond the homepage. So your users will not be able to, say, click on your ALASKA category to go to only the ALASKA section.
That’s why even BIG NATIONAL (US) forums like CITY DATA use categories ONLY to mark major sections on the homepage (eg US FORUMS, WORLD FORUMS, GENERAL FORUMS, etc)… while all the state/city/topical groupings are defined at the FORUM and SUB-FORUM levels.
In other words, in my humble opinion, it would actually be better for you to define PORTS/ALASKA/KETCHIKAN/ as a hierarchy of FORUMS… which you can already do with WPForo… and have a forum structure like this (BOLDS are categories, all others are forums/sub-forums)
