Autocomplete in vscode for schema users

[guettli]

I plan to create a schema.

Users of the schema will use vscode to create yaml files.

I would like to have autocomplete for people creating date of the schema.

At the moment I am unsure whether to use cue or json-schema.

My main focus is not my task (creating the schema) but the convenience for the user who will create yaml files.

Beside autocomplete hovering should show a help text.

Which tool do you recommend to get the best UX in vscode?
