Thanks for the pointers everyone, there were quite a few that weren't on my radar. My use-case isn't a "personal knowledge graph", I'm building an ADU and so I'm looking for a lot of components: todo lists, inspiration boards, costing/spreadsheets, ordering lists, documents.

Notion looks to be pretty capable in that regard, so the knowledge graph options really fell short (Logseq, Obsidian, Joplin, Trilium, Craft). They are likely good if your use case is in their lane.

Anynote looks like a good option, except it doesn't have a web client, just the Android/iOS (and MacOS I guess?).

Milanote sounds like a possible option if my use were more inspiration-board heavy.

I'll probably give Anynote a try, but Notion really does seem to be a compelling product if it weren't for the jackassery that lead to this thread to begin with.
