Just get a NAS and host your own stuff. Nextcloud is quite good, but pretty slow. Seafile is also quite good, is faster, but with less functionality.

Otherwise:

Free:

• pCloud. But i heard they shut down accounts because of copyright shit, but many cloud providers have something like that in their TOS. They also have often lifetime offers like this one: https://stacksocial.com/sales/pcloud-premium-lifetime-subscription

Paid:

• Hetzner Storage Share, if you live in Europe. A managed Nextcloud instance with 1TB space for like 5 bucks a month.
