Ask HN: Open-source project management for non-software projects?

My small, tech-savvy-but-not-tech team needs a project management system -- projects/tasks/kanban, maybe a wiki. But open-source solutions with good UI/UX seem to be, almost inevitably, designed around software projects and I know from past experience something clunky won't get used regularly.

I've looked at YouTrack, Gitlab, Taiga and others -- all fantastic, if only I could sufficiently hide some of the dev-specific functionality. Should I just give up and get a ClickUp or Jira subscription? Or have you found a self-hosted option for non-software project management?
