I'd expect that to be permanent.

the 131072 ones would probably go away without actual reallocation on next write, that seems to be an intermittent issue on HGSTs, losing whole tracks randomly (possibly caused by incorrect disconnect, had that happen once. that thing has quite a lot of power-on counts, q-sense error rate is also quite high). Ofc that's 64kB of data lost.
I'd be more concerned about the other 16 honestly
I have a drive that was decomissioned, presumably, due to 2 errors during long smart tests (within 2k hours, at roughly 30k). Other than that it has perfect SMART parameters, surface tests without issue, and has been running for a year 24/7 no problem now. Other than excessive vibration or a power issue I have no idea what could have caused that.
EDIT: was thinking Firecuda as they are SMR rather than the CMR barracuda, so read that SMR drivers are considered to be better.

because they are different products, they have different amounts of them, there is different amount of them on the market at different prices, and the demand is different
One ZFS drive per pool, with unraid on top? Should be mostly fine. As you say these drives are terrible for writes, but they should be pretty reliable and performant for your workload.
