My only friction with hierarchy-type store of bookmarks is the orthogonal labeling scheme remains poorly or unsupported.

Slapping a tag or two (or many) is bandaid.

Need a way to navigate a tree for a bookmark that is repeatedly tagged and filed across hierarchy.

Perfect example: retirement, budget, investment firms, reviewed

Each day has a focus, and it often arrives differently to a same bookmark.

Handcrafted Wikipedia category tree is a good start but still no navigation panel and a search box thereof.
