One tip in the EU is to consider just renting a Hetzner Storage Share. This is a 1TB (or more) Nextcloud that Hetzner manages for you for 5.11 Euros per month.

A Nextcloud can give you many things at once, file syncing, file shares, contact syncing, calendar syncing, etc.

I have been using this for years now after having hosted my own Nextcloud instance. The space and performance they give you for that price is unbeatable with nearly no downsides. The one downside is that you can't just ssh into the server, but you can even run occ managment commands via their web interface. It is an absolute no-brainer.
