What is a good way to farm rupees?

I came from Breath of The Wild where it was very easy to farm money by killing stone talus every blood moon and I was used to have 30k+ rupees in the middle game. But since in TotK the enemies and their loots are very different , I'm feeling kind of underpowered, not being able to buy as many arrows and armor.

So I would like to get help on ways to gather a good amount of rupees. Btw I think I'm kind of earlyish in the game, I have cleared the wind and lightning temples, but didn't explore much of the depths and sky islands yet, nor the northeast region of the map (lanayru, akkala, eldin). So general directions rather than spoilers would be much appreciated.
