I want to rank my website globally.
The World is too big for a single site. As said, if your site uses a ccTLD, Google will rank you for this country. If it's a gTLD it might help a little bit, but other factors will influence Google, like the IP of the server hosting the site, as well as the different signals your site is sending (like the meta tag language).
So , I assume that if your ambition is to rank globally, it means your site is in English, if so, then you should target North America, and get some crumbles from Canada, UK, Australia. To do so, you can use the Geo Targeting option of the GSC. However, be careful, if you select a geo location , then it's possible that you loose your ranking everywhere else.
If your site features pages in different languages, or targeting different countries, then instead of running a single site, you might want to great one for each language / country , using ccTLD. I am not saying to run the same content on different sites, this would cause duplicate content penalty, I am saying just IF you have pages which are targeting specific countries.
