I'm gonna give reactions to each job just because I need something to wake me up this morning.
Dragoon: Doesn't seem as hugely reworked as I thought it would be. The new BIG DAMAGE attack looks kinda cool, as does the new finisher being an omega-jump, but it's still Dragoon.
Paladin: Did they give Paladin an entirely new combo string or are those light effects on the slashes just a result of the new graphical engine?
Warrior: I don't know enough about WAR to react to this but I liked the big fuckin' boulder slash at the end.
Astrologian: Some very cool effects, and I don't know what any of them do.
Dancer: DANCER LASER
Reaper: It kinda looks like they gave Reaper a repositioning attack, where you do a blade cyclone and then immediately warp-gate away.
Red Mage: Did they REDUCE the amount of mana it takes to get to a full Red charge? Jesus.
Machinist: Sad they didn't add the Automaton King as a level 100 pet upgrade, but the new moves look kinda cool. Seems to be benefitting from the improved graphical touches.
Ninja: I don't really have any notes. More Ninja, lots of stylish shit. The poison belch is kind of goofy but it's a thing ninja do in pop culture so I get it.
Sage: Yep, those are new Sage moves. Damned if I know what any of them do though.
Black Mage: Actually kind of disappointed that the new gauge just leads to another version of Flare. Would've been nice to see level 100 BLMs finally be able to cast a smaller version of Ultima.
Viper: Trance looks pretty ridiculous. Will need to try it for myself.
White Mage: Yep that's white mage.
Monk: That's so many gauges. I'm sure they make sense to long-time monk players but damn.
Dark Knight: The new slashes are kinda cool but I still miss Power Slash.
Bard: I missed this whole section because I was mesmerized by the presence of a GUITAR BOW.
Summoner: Did they add the ability to manually dismiss an Egi before using up all of its charges to skip ahead in the combo? Also what the fuck is with this Stranger of Paradise-ass Sword Bahamut?
Samurai: They really do not know what to do with this job. Adding little "here's some spirit swords! they're just here! they don't do anything!" effects to the same slashes we've been doing for four expansions is just boring.
Scholar: lol angel mode sure why not
Pictomancer: Genuinely looks very fun. I don't think this job is for me personally but I think they've got a clear idea of what they want to do with it and that's refreshing.
Gunbreaker: That's adorable. The new "aerial" combo chain is Squall's Lionheart combo string. I recognize those poses anywhere.
General thought: We're seeing a LOT of jobs that didn't have a "quick dodge" move using them in this video, including jobs that already have dedicated damaging gap closers. Is it possible they've turned some kind of short-step directional dodge into a general action all jobs can use, since we had that in the FFXVI crossover fight?
