Time4VPS also has a storage VPS, which is about on par with Contabo's pricing, but has discounts for first month. Right now they have a deal where you can get a 1 TB VPS for 26 Euros/year (a bit over 2 Euros/month), though renewals are regular price: https://www.time4vps.com/storage-vps/?affid=5294#annually (affiliate link, I use them for regular VPSes)
In comparison, a 1 TB HDD costs around 40 Euros where I'm from, way cheaper than most other options in the longer term, even with a backup drive or two added into the equation. Uptime remains a challenge then, though, as might data correctness long term and time spent validating whether backups actually work as expected (and keep doing so).
Hetzner gives you 1 TB for Nextcloud for ~5.20 Euros/month: https://www.hetzner.com/storage/storage-share
