Just get your affairs in order. Lay out your last wishes in detail. Make sure the will is drafted meeting all legal requirements. If there's someone that you DON'T want to get any of your money or stuff, explicitely have that put in your will. There's nothing wrong with writing notes or emails, in my opinion, to family members and friends, as long as they aren't being delayed-sent like a year after you die or something like that. I would definitely destroy devices and hard drives instead of just deleting material. Make sure any passwords you have jotted down for sites that you'd rather not have anyone know about are destroyed and can't be found. I don't know why there would be suspicion to adding beneficiaries to back accounts. All accounts should have beneficiaries on them, as long as you have beneficiaries to put on them. Banks know this and expect it. If you're using something to ctb that is traceable, say like N from certain bottles, maybe transfer the N into another vessel and dispose of the original bottles way beforehand the time you actually ctb.
