Hetzner‘s storage share product line offers a managed Nextcloud instance. I‘m using them as I didn‘t want to care about updating it myself.

The only downside is you can‘t use apps/plugins which require additional local tools (e.g. ocrmypdf) but others can be used just fine.

Calling remotely hosted services works (e.g. if you have elasticsearch on an vps and setup the Nextcloud fulltext search app accordingly)
