FF14 Endgame?

[Kandraxx]

So I finished all of the MSQ now and got a couple classes at 80, but I read the endgame is basically housing, collecting cards, mounts, pets and doing side activities. This can’t be real?

Ok, I knew that pvp doesn’t exist (in reality, not technically) from the beginning, but what is the pve endgame, as there doesn’t seem to be any real raids? Do the 24-man raids have more difficulties than the default one?

I read about ultimate modes that are supposed to be hard, but from looking videos it’s just circle arenas where you dodge things for 15 minutes while doing your rotation?

I unlocked a raid finder in Idyllshire, it says that it will need progression with a set group, but it has only one fight in it (leviathan) so I don’t think it’s still relevant content.

Are there more raids to be unlocked (or modes), that have real mechanics and a real raid zone with trash mobs and all? Like in you know what game. This is definitely confusing because sometimes I go to old content and there are suddenly new (+) quests that add bosses but it doesn’t look like 80 endgame.
