And the sitemap section always says
No referring sitemap I will be so glad if you can help me with my website Crawling and indexing

Ummmm... the "error" clearly explains the reason that the url was not indexed....  because that content exists at another url, as defined by the canonical tag.

Yes, make sure the urls in your sitemap match the canonical form.

You have quite literally no content to index, so it's really way too early to stress about Google. The site has been crawled, Google wasn't interested.
You should however make sure that your site is only reachable through https, and remember to use https with Google tools too. Makes it easier for when Google does get interested.
