Ok for a longer term project, I would suggest that you learn how to self host the services that you depend on.
This may be time to go into things like converting an old PC to a network attached storage or NAS and self host from there. Look into TrueNAS, or if you are less tech inclined, something like HexOS. From there you should learn about how to do backups and how to add apps.
Its a rabbit hole for time and money. Do have a look into it if you have a deep need of owning your data.
Its a bit unfortunate for Apple but they were legally forced and there is not much they can do. Its up to you to secure and make private your own data.
