I would also like to ask everyone about suggestions for deep storage of personal data, media etc. 10TB with no need for access unless in case of emergency data loss. I'm currently using S3 intelligent tiering.
Wasabi is the best option for you. 10TB would be around 60$/month and they offer free egress as much as your storage. So you can download upto 10TB per month.
Also read their free egress policy first: https://wasabi.com/paygo-pricing-faq/#free-egress-policy
