RAID1 for homeserver, ZFS, BTRFS or ext4 ?

Hi, everybody,
I own a Terramaster F4-424 Max with following storages installed:
2x 1TB M.2 NVME SSDs
4x 3,5" HDDs
1x 32GB NonECC RAM

My plan is to use the 2 NVME SSDs as a RAID1 for the OS and a couple of VMs. One VM shall be configured for OMV using the 4 HDDs via PASSTHROUGH.

My question is, what filesystem would be suitable for my scenario?

- ZFS: I tried to install a ZFS RAID1, but for some reason the system doesn't boot.
- BTRFS: I installed the system on BTRFS RAID1, this works, but I'm not sure if it's a good idea, cause BTRFS is marked as "Technical Preview".
- ext4: ext4 is the default fs for ProxmoxVE but I haven't tried this configuration yet. Would it be a good idea to install a recent debian on a software RAID1 with ext4 + LVM and install ProxmoxVE as mentioned here
- Or I skip the idea of RAID1 and use the default ext4 + LVM setup, 1 NVME SSD for the OS and the other for VMs .

What do you think about these scenerios, any suggestions, any different scenerios?

Regards Pete
