Gold farm in perimeter 1.21.5

Hi! Im mining a perimeter in the nether for a gold farm and im halfway through, so im already lookibg for what farm I'll build.

Im looking for a fully afk farm with no autoclicker or anything like that. I know that the most efficient efficient ones use looting, but I don't want that, nor the gold farm that uses ghast.

The perimeter is not on the world border, so I can't do the border gold farm. I also want to not break when I update (like the spear pigman that broke some farms). I looked through the TMC discord and a few more, and a ton of posts around here and most of what I see is in the nether roof or looting ones.

I just need a fully afk gold farm in a perimeter. If it has a bartering farm linked, even better.
