Several issues with google indexing and pagespeed insight

Basically when i search to see what links google can see, SITE:xyz.com i get couple of them mainly front pages, but never blog posts. However, when i test see if the blog post is indexed in the in search console it says it is.

Also there are other pages which does show on SITE, but says is indexed.

Also when testing the score for the site, it says site is not using HTTPS, that's completely wrong, because it is.

1. Should i be worried about the indexing issue, or if search console says it's indexed then leave it as is.
2. Also how can i solve this issse of no HTTPS when it's obviously wrong.

Site is about 3 months old.
