Ask someone with a crown icon to invite you to the Novice Network. They are usually very social, and mentors will help answer all your questions and may queue into content with you.
You could also join a Free Company. These are known as guilds in other MMOs. To find one, you can visit
https://eu.finalfantasyxiv.com/lodes...munity_finder/ but login and set your Active Character first.
There, you can also find linkshells and cross-world linkshells. These are chats you can join that have people with likeminded interests.
You can also visit busy city states and talk in /shout. On most worlds, the busy city state is Limsa Lominsa's Lower Decks, but other locations can be populated sometimes too.
You can setup recruitment for content in Party Finder. The people who join will usually be more social with you because you were not randomly matched with them.
You can also join discord servers. A large amount of the community presence is on there and most discord servers have an "other discord servers" channel.
