I use archive storage class on google cloud, to store old movies and wedding videos, pictures of old vacations.

For everything else I use paid onedrive subscription. The biggest problem is user interface with s3 like storage and predictable pricing because remember you also pay for data retrieval and other storage apis, with dropbox etc you pay a fixed amount. Every year or so I roll over data into the bucket.

But for infrequently accessed data its fine.
