My solution for syncing keepass between Linux and iPhone (works with KeePassDX on Android too) using Nextcloud:

My Linux computer is running Incus, and one container is my Nextcloud server.

I have created a folder ~/nextcloud where my keepass.kdbx is located.

KeePassXC is using this file directly and since it's a local file it's always accessible.

I have mounted ~/nextcloud inside the Incus Nextcloud container as /data.

In Nextcloud I have monuted /data as a folder for my Nextcloud user.

In KeePassium in iPhone I have set it up to use WebDAV to my Nextcloud server and then choosen the keepass.kdbx file.

(This way I can also easily share any file between Linux and iPhone)
(I know there are other ways to do this, but since I want to always have access to keepass.kdbx on Linux even if Nextcloud is not running this solution best fits my needs)
