Once again I'm given another blue outline on a box. I'd really like to remove it as it's completely inconsistent with our site colors. I'm hoping for a solution and not to be told that it's an accessibility thing that Editor X won't allow us to change.

So found out this is an accessibility thing and would need to toggle it off. There isn't an accessibility wizard built-in though the team has a feature request you can vote on here. https://support.wix.com/en/article/editor-x-request-accessibility-wizard
