They're all outdated as far as abilities go since many things were updated in Shadowbringers, but the basic gist/role of each job is still the same.
The FFXIV wiki pages and official pages also have decent explanations of each job too.
Bear in mind that you have different options depending on what level you are and what story content you've unlocked, and whether you want to spend any money.
1) Fresh characters have access to Gladiator/Paladin, Marauder/ Warrior, Pugilist/Monk, Lancer/Dragoon, Archer/Bard, Thaumaturge/Black Mage, Conjurer/White Mage, Arcanist/Scholar/Summoner
2) At level 10, after finishing your starting jobs level 10 job quest you are able to go and open up every other job in the game, which includes all crafters, gatherers and the Rogue/Ninja
3) At level 50, if you have Stormblood registered to your account, you are able to unlock Red Mage and Samurai
4) After gaining access to Ishgard by either buying a story skip potion or completing all of the story quests leading there, and having a level 50 job you can unlock Dark Knight, Astrologian and Machinist
5) At level 60, if you have Shadowbringers registered to your account, you are able to unlock Dancer and Gunbreaker
Hope this helps a little bit. Good luck!
