pass probably isn’t for you then, unless you find a wrapper or something that lets you put all in one file. I’ve switched to keepassxc as well, I could never get the browser integration to work with pass.

No, only the file contents are encrypted. The file names and folder structure is visible to anyone who has access to the files.

The files themselves can contain a ton of stuff if you want, but the convention is to put the password on the first line and that’s what “pass -c my/file” will copy.
