Installing Drupal

Long story short: I am a newbie Drupal developer looking to land a project to revamp a static WordPress site in Drupal. The project has a pretty big scope (CMS, media center, Role-based login, API integrations, ECommerce, Microsites) so I may very well be in over my head for this project, but I am also excited for the opportunity and the chance to expand my skill set by learning Drupal!

Hello there. 

Newcomming to Drupal community, I have chosen Drupal (8.7.5) as the base for getting into deploying web solutions based on CMS for further projects, and really would like to understand architecture of this platform. What is the best way for making a local server on Mac for further different web development?

I currently have a Drupal 7 site (https://thehappyscientist.com/) that has over 1800 pages, makes heavy use of the Views module (over 300 views), and has a large, subscriber database.  I need to move to Drupal 8, and am trying to decide between trying to migrate the site to D8, or starting with a blank D8 site, and rebuilding the site to clean it up and remove unused fields, etc.  

I have been playing with Drupal, practicing some installs on my unix shell ISP (with no root access). 8.7.4 install set up a sqlite database, but I scrapped it all and tried to re-install using 8.7.5 now that the security patch came out, and now I don't have the sqlite option, on the setup database page it just says:

Database type

Hi,

How do I get a bookmark icon in web browsers using Drupal 8? I have changed the favicon 16 x 16 image to my site from the standard Drupal favicon but when I go to bookmark my site in browsers I get the letter icon rather than a nice brand image like other sites I bookmark.

How can I get a nice brand image icon when I bookmark my site on browsers like safari etc?

Thanks
