You want a no-maintenance hosted community with a large plugin marketplace and don't want to touch server config.

What is NodeBB?

NodeBB is forum/discussion software built on Node.js that presents itself as a 'next generation' alternative to older forum platforms, with real-time posting, mobile-first responsive design, and native chat/messaging built in. It's open source (available on GitHub for self-hosting) but also offered as managed cloud hosting for teams that don't want to run their own server. Notable features include ActivityPub integration for connecting forums to the Fediverse (e.g., Mastodon), single sign-on, customizable themes and a plugin ecosystem, and built-in SEO and GDPR-compliance tooling. It powers community forums for organizations including Qt, Vivaldi, Opera, and MOZ.
