I guess the easiest thing is to not be opinionated about names and just use whatever is entered within the editor.
The other option would be to let you classify the page as a “tag, category, post or page” and then prepend the class to the filename (i.e., category-NAME, page-NAME, etc)
Currently Blocs exports anything that is not a specific template type(name) as a custom page template.
This is basically to help users not well versed in WP template development get up and running without needed to know how page template files should be named.
I can loosen this up a touch and check for custom categories and archive pages based on the naming.
