One of the things that stands out for me from FFXI was a lot of their more interesting holiday events. For example, the "Test of Courage" in their Summerfest event(s!?), where you were ported to a dungeon as a level 1 and had to sneak around to collect an item. Even the goldfish scooping which was arguably less interesting was also a lot of fun, and really engaged you with the world. There was a sense of awe, going into remote desert towns and scooping for goldfish, watching beautiful fireworks going off at night in the city, etc.
The new Sunshine Seekers event reminded me a bit of this.

There were also end of year events with giant trees or whatever that would blow you into another zone? Not every FFXI holiday event was amazing, but many of them were much more varied and interesting than anything we've seen in FFXIV so far.
Pretty much every holiday event in FFXIV is "talk to this guy" or "do that FATE", with very little of value beyond that. It would be nice if the dev team tried to engage the player with the world, especially during holiday events, more than simply redecorating the town a bit. Also, if FATEs are going to be used for everything ever, they should probably be made more interesting than a mindless xp grab.
It's not like the dev team needs to make new monsters or create crazy bosses or something for holiday events, just code something very simple that is also interesting and fun, rather than just shove a bunch of talkies and FATEs into every single event and call it a day. Zerging balloons to death for summer isn't really any more or less interesting than zerging any mob type during any time of year ever.
