Been here since 2.0 and always maxed out every job, this is generally the right answer. You have enough time from now to Endwalker release (Semptember-ish) to fully gear at least 2 job roles, maybe 3 to 520/530. Once EW releases, that gear will get you easily to lvl 85 or so without having to change any gear out.

Meanwhile, while you're leveling those 2 or 3 jobs, the 520/530 gear will be buyable via poetics and you can continue to get gear for the next role. When you think about it there's only 7 sets of gear you need to obtain between the 18 jobs. Fending, Striking, Maiming, Scouting, Healing, Ranged Magic and Ranged Physical as the jobs share that gear between them.
