*CoBlocks (free)
*Advanced Gutenberg (free)
*Otter
I didn't add Co-Authors Plus (https://wordpress.org/plugins/co-authors-plus/) as it hasn't been tested on the latest version of wordpress. There are other plugins that offer equivalent functionality if I need one later.
Other plugins I might want are:
*Revive Old Post (share with twitter)
*Optimole (optimize images)
*WP Rocket (implement cache)
