Recommended file system for a very small environment?

[DrNoname]

I'm planning to migrate my Windows Server 2019 with about 500 GB and a few Windows 10 clients currently running on ESXi to Proxmox.
The Proxmox host will be used "standalone" on a single physical server, without failover servers or SAN, the workload will not be very heavy.

Which file system should I choose, LVM with a RAID controller or ZFS with software RAID?
Is it advisable to install Proxmox on one SSD and have a separate disk (RAID) for data or should I put system and data together on one SSD?

It depends on what storage you present. if you're using a raid controller, lvm, if you're presenting JBOD, zfs.

s it advisable to install Proxmox on one SSD and have a separate disk (RAID) for data or should I put system and data together on one SSD?

it is, for many reasons. separate ssd mirror for your system partitions, seperate disks for payload. If you dont mind a failure downtime you can forgo the mirror on the boot device, and keep your vm settings backed up.
