Object vs. Item
I actually don’t think object is difficult for most people to understand. It does have a technical background, but not so much so that I don’t the average person on the street can understand. Object is a pretty generic word that can be used for anything. Which is why I think it fits here. You can create any kind of object with whatever properties you want
Queries vs. Curated Collection
I’m fine with using query in that way, but when I think of collection I don’t think of a bunch of manually selected things (which may or may not be different). Typically in my mind collection means a group of items/objects that are all the same (or similarity). For example I might have a collection of apples or a collection of fruit. But I would never use collection to describe a group of items that included things like animals, cars, and books. Yet this is how collection is (currently) used in Anytype. You can group a bunch or fandom object types into a collection. Not sure what a better alternative is, but I think a collection should be a group of the same object (ie. this post Help with the naming of Anytype's 'List')
Vault vs. Account
I agree that vault is a bit confusing (and has been to me). Some applications have “vaults” within their main application (eg a note taking app that stores everything in plain text except for what you put into the vault). For Anytype the whole application is your vault. So I agree using the language of account is better here.
View vs. Layout
a view should be the combination of sort, filters, and a ‘layout’
Agreed
Property: Object vs. Property: Relation
I already though this property was called relation? If not than I agree relation is good.
Editor vs. Canvas
Why not just call it the “content window?”
Channel vs. Space
Con: Can be misunderstood as a workspace with granular permissions.
I thought there was mention of adding more levels of permissions to the spaces? Either way I think spaces is better. Typically other applications (Discord, Slack, Matrix) all use channel as being apart of the same server. In Anytype the spaces are more like servers. Therefore, I think you should stick with sapces here.
