How to prevent discovery of URLs by search engines?

I crawled my WordPress site using the Screaming Frog program and noticed a few issues which might have SEO implications and was hoping someone could help identify the problem (if there is one).

N.B: I have obscured the domain name in the image as I do not want it made public.

The canonical URL for my domain is prefixed by https://www but as you can see from the tree graph image below, there are a number of URLs accessible under the http protocol and the non-www version of the domain. Those URLs are non-indexable but I’m curious as to why they’re accessible at all. I was thinking that shouldn’t happen if the proper redirects were in place.

In the WordPress admin settings I have entered the correct version of my domain for the WordPress and site addresses (i.e., https://www)

It’s possible my .htaccess file might require editing so I have pasted it below:
