I would also add:

(set-fontset-font "fontset-default" 'symbol "Noto Color Emoji")

To get support for Emojis, Dingbats, and other symbols. Though I've noticed Noto Color Emoji doesn't seem to have it all, for example it is missing Dingbat 278A, but if you install Symbola as well you should have those covered too. Here's how to set it as your fallback font for symbols missing from Noto Color Emoji:

(set-fontset-font "fontset-default" 'symbol "Symbola" nil 'append)
