Take your time. You'll get there eventually. If not this expansion then the next because you are constantly getting more jobs to high level ranges. Don't be afraid to swap between every job if they start to feel boring. There is no rule that you have to do them one by one. The level ranges can start to be boring as well so if you have jobs at different levels you can pick more freely.
And I can't stress this enough. If you have goals to complete other content which gives xp then make sure to complete those goals before everything is capped. That way you are not wasting time on leveling and you actually finish other things in game. I cringe at the thought of farming bicolor gemstones or wolf marks, leveling trusts, completing Yokai or beast tribes and doing PotD/HoH/Bozja with capped characters.
If you really dislike a job or two, you have the option to do daily Frontline challenges on other jobs. The xp goes to whichever job you queue with even if you swap jobs inside the instance. Occasionally you can dump all the wolf marks on a hair style or a minion, which is pretty neat.
