You could use the Save Editor, but the save editor is really just doing exactly what cheat tools like Jnoex, SXOS and Edizon do minus giving you the freedom to look around yourself. I can't comment too much on it since I don't use it for anything other than a visual reference for villagers. I use a combination of Noex and SXOS personally but any cheat engine with a search function is all you need for what you are trying to do, and since you said you were trying my cheats I'd assumed you had one of them.
There is no debugging involved here. That work was already done the very first time. We already have the values we need. The hard part has been done for you.
That's the thing though. I'm not using SXOS, and Edizon can't be used to search for any values since it can't recognize ACNH for loading cheats or backing up/restoring save files. There is the Edizon overlay, however I'm not aware of it being capable of searching for addresses like this. SXOS and Edizon do use the same cheat method however, so the codes are the same between SXOS and Atmosphere.
EDIT: I found the Noex you were talking about. I'm looking more into, and thanks for letting me know about it as well.
