As it was said, the best option is to have separate storage for backups, ideally backup NAS. IT will also give additional protection and would help you to fit 3-2-1 backup rule. As for encryption, rclone should handle this. Alternatively, you may check starwinds vtl with backup software, cloud provider won't be able to access the data stored inside of the virtual tape, but you should check if it works with google drive.

As it was mentioned, it not enough experience and info about those drives as a long-term storage. Also, if you want to keep your data as long as possible, you should consider having several copies of the data. So, even if the drive/array failure occurs you are still good by restoring the data from another copy.
Well, it is still not comparable to the $/tb ratio offered by HDDs and I don't really think it will be close to it in the future. Also, they are used for different use cases, so I do not see any reason to compare it now.
It really depends there on the games and their disk usage. I do prefer to have NVMe drives for my games, simply not to even think about possible issues with disk performance.
I understand that it can be costly depending on the required capacity, but I do not spend anything on backups for them since they can be easily redownloaded.
I prefer to spend more on Samsung externals, I have t7 and had no issues with it so far. It's kind of getting hot after some time, but, I believe it's the case for all external SSDs.
I have internal crucial NVMe and it works without any issues as well, not sure how their externals are.
I do not recall any issues with it. So, it is should be fine as others in terms of reliability.
I see, than good luck with finding good deals on the hardware!
You won't see any difference and it's not really applicable on the personal usage. You are not going to have the amount of drives they use, that's why.
I do not see any issues with your configuration.
You can really use anything there rclone with any cloud provider, backblaze personal and etc. You can also encrypt the data before uploading it to the cloud, so it won't be accessible to cloud provider, as alternative to it starwind vtl can be used to upload the data in parts.
They are reliable as other enterprise drives from WD and Toshiba. Really not much to say here, check also if they have valid warranty.
As it was mentioned, you can implement SnapRAID for redundancy and better data availability. Since you are running your system on Windows, it might make some sense for you to use Backblaze personal as a cloud backup https://www.backblaze.com/cloud-backup/personal
Also, try to have a local backup somewhere (external drive or backup NAS)
You could usually see weird values on Seagate drives on 3rd party software which gets the smart data, and usually everything was fine with the Seatools. I wouldn't be much concerned since Seatools showed that the drive is ok. Actually, if you have proper backups, I wouldn't really worry about it.
