I always wanted to hear the experiences someone more knowledgeable.
I may not be that guy, but from my research, magnetic storage seems to be the best option.
but wouldn't hard disk drives risk getting erased when magnetic fields in the future either become too prevalent
If they were naked, yes, but they sit in a steel cage inside the drive, which Higher power fields would be toxic to us, as lower power fields are already proven to impair brain function, so standard HDDs *should* be fine against the densities we are likely to see.
I looked up LTO magnetic band drives and decided that it wasn't worth the cost _yet_ (I will track them), for now I decided on an affordable CMR HDD that will have more than enough space. I would probably not write to it that often, but definitely have to be keep in mind to replace it every ~4 years, it costed about 100€ for 8TB which is not a huge sum to me. I had multiple HDDs fail to me but none that were properly powered like this, just the plug and play ones.
