There are only a couple cloud companies I?d recommend storing data with, for precisely the
reasons you give. Storing with two would be advisable. Or a hybrid on and off premises
approach. For my photography archives, I?m taking a hybrid approach, recent changes are
backed up to Drobo, everything is cloned and kept offsite, and then all photo?s are also
sent to Cloud Storage. Once you start planning for Backups as part of your storage
purchases, it becomes easier to handle.
On premises has the exact same problem as tape. You must have a refresh plan. That?s the
advantage of off prem, you don?t have to worry about refresh.
For archives to be done right, you need at least two copies, excellent documentation, and
a solid refresh plan.

Cloud storage as in "handled by some cloud company" is only as good as the
longevity of that company. If it shuts down suddenly because of poor management or fraud,
your data is almost certainly gone. Or it might end up disclosed to whoever pays pennies
on the dollar for the company assets.
On premises, sure, but now it's just a question of what medium you like. Those
storage devices probably use disks, or maybe flash storage. How long do those last? For
example, take a look at the "power off" retention time spec for flash storage,
it's surprisingly short. And how long is the relevant software available?
(That's a concern for any kind of digital storage, of course.) ...
I?ve failed to see any reason behind your questions. If you?re looking for a long-term
archival solution, look to cloud storage (either on-prem, or off-prem). Sure tape is
cheap, but when you start looking at other costs, such as storage and handling, it becomes
expensive.
