Replicate Notion's 'databases', with relation properties?

I have been making lists of some plugins in the space, with pros/cons etc, but I haven’t settled on anything that’s solid. Here is a summary. What do you think, and what else should I be looking at?

  1. DB Folder - GitHub - RafaelGB/obsidian-db-folder: Obsidian Plugin to Allow Notion like database based on folders
    Tables only, some design quirks, now supports bidirectional links.

  2. Obsidian Database Plugin - GitHub - tomaszkiewicz/obsidian-database-plugin: Enables creating databases based on files in Obsidian - like Dataview, but with editing!
    Similar - tables only, supports file links as a column type.

  3. Notion-Like Tables - GitHub - trey-wallis/obsidian-notion-like-tables: Your premiere tool for creating and managing tabular data in Obsidian.md
    Just a single table with frontend niceness but no real connectivity.

  4. Projects - GitHub - marcusolsson/obsidian-projects: Plain text project planning in Obsidian
    The only one known to include table, gallery, board and calendar views. But exists in a self-contained silo, not in the file tree. More importantly, doesn’t work on iPad.

  5. Kanban - GitHub - mgmeyers/obsidian-kanban: Create markdown-backed Kanban boards in Obsidian.
    File is present in the tree. Nice Markdown under the hood - flip side, meta data are not set in the card files themselves, only in the kanban file. No real file interlinking except through normal note links, as it’s not really a database.

  6. Cardboard - GitHub - roovo/obsidian-card-board: An Obsidian plugin to make working with tasks a pleasure (hopefully anyway).
    Doesn’t appear in file tree - also I don’t understand it. Tasks-centric.

  7. Dataview - GitHub - blacksmithgu/obsidian-dataview: A high-performance data index and query language over Markdown files, for https://obsidian.md/.
    Only for output display, not project management/input. Query language norms not so friendly.
