People should really forget about classic FF jobs being in FF14 yet still functioning as classic FF jobs. Look at BLM and SMN and others to answer your question. We have no elemental wheel and the elements are split between 2 jobs.
The battle system is also different.
Based on what we know x base class turning into BLU and learning 5 spells via quests is the most possible since that's how most jobs here have done it. We can also get more spells every expansion.
