Installed SSL, what's next?

Hi
Can you guys guide me what to do exactly after SSL was installed?

What I did so far:
1.Installed Really Simple SSL Wp plugin.
2.Added the new https version to search console plus www non www version ( there are 4 different versions in search console now)
3.Changed the urls in analytics.
4.Submitted a new sitemap (every url starts with https)
5.Fetched the site as google for faster indexing.

Is there anything else I should do? I have checked 5+ articles they all provided different infos.
Do I need to change every internel link manually to https?
Should I change anything In HTACCES?

Some advice would be highly apreciated.
thanks

Are you making PBN or Regular Blog ?

Changed my "money site" from http to Https because of the warning what I got in webmaster tools.
Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.

I knew this already, thanks for the valuable info.

redirect all the http to https via .htaccess, also make sure all your pages with the green padlock

Switch your http links to https from your database, if you're using Wordpress there is a plugin for that
