As to how thaumaturgy works, it's in relation to game mechanics of how much mana thaumaturgy uses in relation to other magick spells. Also how their personal mana depletes quickly, then refills. Also energy is not infinite, therefore thaumaturges *must* have a source for their mana, else lore-wise it would be noted that they can only cast spells for a certain duration of time, which we know is not the case. So you're right, much of thaumaturge's mechanic lore is based in-game, not in quests. But until I have anything to contradict that, I will stick with that interpretation. Especially since SE in general does a good job of keeping in-game mechanics in line with the lore for said job.
As to conjury, we know that spells such as cures aren't immediately dangerous to use without leaning on nature from the conjurer quests. Sylphie casts conjurer spells using her own mana for at least weeks, maybe longer, before she feels ill effects. And her mother even longer.
Personally with my character, he has an extremely low mana pool, so the only spells he can cast without feeling mana-deprivation effects is arcany. From what I understand from my arcanist lore friends, arcany uses a spark of your own aether to guide the aether around you through the enchanted ink, which amplifies it. But that's another, very interesting subject.
Was just talking with my S/O actually about how interesting it is that theoretically, I think a conjurer/thaum could use their magic without their weapon, while an ACN would be totally screwed if you took their grimoire away.
