I've worked for a company where some users managed very personal informations on behalf of other users, like, sometimes, very intimate data and I always fought product on soft deletion.
Users are adults, and when part of their job is being careful with the data _they_ manage and _they_ are legally responsible for, I don't feel like the software owes them anything else than a clear information about what is going to happen when they click on "CONFIRM DELETION".
"Archive" is a good pattern for those use cases. It's what have been used for decades for OS "Recycle Bin". Why not call it Delete if you really want to but in this case, bring a user facing "Recycle Bin" interface and be clear than anything x days old will be permanently deleted.
