I'd probably post in the
Brynhildr server discussion forum as well, rather than just in General Discussion, unless you're willing to change servers for an FC.
I know there are FCs out there for pretty much every type of player. FCs that are for diehard folks who want to run the highest-tier content immediately, FCs that are just chill and chat with each other but don't really run events, FCs for folks focused on roleplaying in-game, FCs that try to be inclusive of all player types, etc. What I don't know is what any of those FCs are for your server, specifically, which is why you may have more luck in your server-specific discussion forum.
Another place to check would be the
/r/FFXIVRECRUITMENT subreddit, which is more generic (but also probably gets more traffic than your server-specific discussion forum here, as those do tend to be a little low on the activity side). It's not a discussion forum, as people can't even reply to posts; it's just a place to post "hey, I'm looking for [an FC/a static/a linkshell dedicated to hunts/whatever]" notices, along with information on how anyone who has a suggestion/answer can contact you.
Good luck in finding the FC that matches your playstyle; I know it's got to be out there, somewhere.
