Adding redundancy after installation

Dear Proxmox Community

I recently started renting a dedicated server. The Provider allows for automized installation of Proxmox VE 6, which I've chosen.

The server has 2 SSD's of 74.5G and an additional HDD available. However, the installation was done (as to be expected) on a single drive /dev/sda. I want the server to operate with data parity (Proxmox Boot and VM's) on the two SSDs. I also thought about running the two SSDs in a ZFS rpool. However, this could get difficult since KVM can't be provided with this server. But I'm not planning to run ZFS without ECC memory anyway.

What would be your recommended way of installing Proxmox VE on the given hardware? My priority is data redundancy as well as being able to take snapshots.

Below are details about drives and partitions by the automized installation. Partition sda2 holds the operating system.
I have access to a recovery system with which I could make some operations on the disks/partitions.

Thanks very much for your opinion.
