Mail is randomly moving some emails, including unread ones or whole ongoing threads, from my inbox to the archives folder. It happens with most of my mail accounts, including my icloud account. I tried several fixes found on the net, including this website, but none of them works (i.e mailbox behavior setting, rules etc...). Any kind soul found a solution?

I have never seen iCloud auto-archive an email. I don't even see any settings to make that happen, neither in Mail nor in iCloud.com. So, I have no idea how that is happening.
As to other accounts, Gmail essentially does that always. It isn't really IMAP, but pretends to be. It doesn't have folders, but "Labels." Multiple Labels can be assigned to a message. All messages come into your Gmail account with both an "Inbox" label and an "All Mail" label. The All Mail Label is mapped to the Archive mailbox in Mail.
Because it isn't really IMAP, messages on Mail end up in one folder or the other, and possibly both--quite abnormal for IMAP. The fix is to not use Gmail (or any other non-standard IMAP-like service) in Mail.
You can disable the viewing of Gmail's All Mail in IMAP in the advanced settings for Gmail under the Labels tab. That won't stop Gmail from marking them as both Inbox and All Mail, but you won't see the duplication in Mail.
Thanks for the answer.
I saw it happens today repeatedly, in front of my eyes: emails disappearing from my inbox and going to the archive mailbox. Some emails I had moved back to the inbox found their way back to the archives by themself... It happened with both my icloud account and my work account (standard IMAP). Funny enough, none of my Gmail accounts were affected.
