I'm curious if there are any side effects for hard drives that are sitting on a shelf for a long time (years). Should you plug them in once in a while to keep them happy or anything like that?

Since hard discs are mechanical devices with bearings for the platters to spin on, I'd expect that it would be a good idea to periodically spin them up to help make sure the bearing doesn't seize.
Long ago I had a 20MB hard disc (yes, megabytes; this was a very long time ago) that had a 'stiction' problem (
Stictionw). This wasn't a problem with the bearings, but of the heads sticking to the platters when the device wasn't in operation for a while. When powered up, the platters wouldn't spin because there was enough friction between the heads and the platters they were resting on before spinning up. I managed to get my data off the drive by taking the top off and giving the platters a little nudge near the hub.
I don't know if today's hard discs are susceptible to that same problem, but anything with moving parts may find it difficult to get going again after being unused for a long period.
So if you decide on using hard discs, I'd also work on a media rotation plan - that might be a good idea regardless of the medium you choose. It might also be wise to use something like the parchive format (
Parchivew) so that you have a chance for recovery if some pieces of the data were corrupted/lost. (Disclaimer - I haven't used anything like the parchive format myself, so I don't know how usable and effective it is in practice).
