Hi and welcome! I can't offer much help in regards to a leadership role in an FC regarding RP, but as far as just picking it up and testing the waters, I'd think starting off with some simple social RP might be the best to start! If you want to get a feel for what that would be like, you can always lurk around popular RP locations--whatever those might be on Mateus--and/or attend events where people will inevitably gather for RP, and get a feel for how others write/portray their character and pick out what you like about different styles. Roleplay has all sorts of different faucets that different players will be attracted to. Whether it's more social aspects, fighting-oriented things, monster hunter stuff, more story-driven arcs, etc. So, while this is-again-just speculation as I have no experience as an RP-FC leader, I'd say find which entertains/interests you the most, since that's what you'll be arranging and such. You want to make it as much fun for you as it will be for others!

Welcome to FFXIV! Yes, thankfully now there's World-visits, so you can connect with players on the data server! If you need any help in-game or a healer through content, hit me up!

It might be easier to answer if you specify where around you left the game at? What expansion/patch etc. Else, some of these answers may be longer than necessary.

Welcome to FFXIV! Honestly the best things to keep up with to start--and honestly throughout--within the game are Story quests and your Class and/or Job quests! Going through story is what will unlock a bunch of content for you! Glamour is thankfully now unlocked much earlier on, and is collected in all sorts of different ways, from dungeon drops, crafting (or buying on the marketboard), raids, etc. The Glamour Dresser is your friend when it comes to making outfits called Glamour Plates. Which is basically a loadout and costs one glamour prism to apply to currently equipped armor. Your card looks great!

Digging the aesthetic / decoration!

Welcome! Unfortunately, I am on the Crystal data-server, so I'm no help when it comes to rp locals on others. I don't play a Viera, so I haven't researched myself much, but here's a few links that may be a good starting point (they may very well be very similar in text; I skimmed mostly). Here, here, and here! (this last one being some in-game screenshots of an NPC explaining some 'facts'. As far as Jobs, I've seen and read experiences from people that play these differently. If you've done any of the job quests, you might be familiar with the soul crystals you can equip of that job. I don't have the in game text really, but as far as i recall, these stones can hold the experiences and memories of the previous skill-holder--which is why I assume WoL (Warrior of Light) can get a hold of one and be really amazing suddenly. Most job quests will give you some insight behind what that job does and how they work. I've seen players that RP having these soul-stones as well. As for myself, I don't have characters with particularly amazing abilities, or if they do, I kind of build my own facet based around the idea of an aether-fueled world. Sometimes the aesthetic or fight-style just fits with my character, and that character may not have all the fancy abilities listed on my skill bar. You basically have the right of it as far as rules? People come in all sorts and bunches, and everyone is going to have different boundaries and expectations. As long as you're overall respectful, you should be good. Most will /tell you if they're feeling uncomfortable. Don't be afraid to message others either for the same reasons, or if you want to ask to come into an rp scene between people or something. The ffxiv community has probably been the most welcoming in comparison to most MMOs I've played? But also the most sensitive. So, just be mindful. Sorry if this wasn't much help! I hope you can explore rp in your data server soon!
