By far the most accessible option I found after a decent internet search was the ridiculously huge apple orchard you find on Satori Mountain, east of Central Hyrule, right next to Sonapan Shrine. A full harvest will give you about 150 apples & a few golden apples. If you cook all of these into meals (5 apples together) you can make a bunch selling them. Keep the console powered on next to you for about half an hour and they will all respawn and you can just do it over and over. And you never have to worry about having enough food!
Bonus tip: Farm arrows from the Battle Talus outside Saharsa Slope Skyview Tower southeast of the castle.
Bonus bonus tip: Chopping grass with your weapon anywhere in Hyrule Field has a decent chance of getting you a Restless Cricket. Cook four of them with a monster part of your choice for a full stamina circle elixir.
I haven’t found a need to farm anything other than the above so far.
We had a little NAS in the office, tied into AD and everything. It was called “Hollywood”. Its contents was “donated” by the staff lol.
Edit: Sorry about the acronyms peeps, my bad.
