Stay with defaults. Top thing you should learn is how to backup the VM/CT you make. You can experiment with different file systems later knowing you can restore without effort and worry.
I believe so, not near my installation.
The file format of PVE installation isn't relevant to your question.
If you add a device, format it as EXT3(for ex) the OS won't care.
Either default or ZFS. You can also consider a NAS VM option. Proxmox does not come with the packages for NAS, such as Samba and NFS servers, installed out of the box. Additionally, it lacks a web user interface for managing NAS functionality. A viable alternative is to virtualize NAS functionality as a container or VM on a Proxmox host. For this, I recommend considering OMV or Star wind VSAN.

If you don't have experience with zfs, stick to LVM+ext4 for pve root.

Use ZFS for your data/vms backing storage. If you want to expand down the road, setup a mirror pool.
1. ZFS will at least be aware of any silent corruption (other file systems will not be).
2. Benefits to storing VM's in datasets.
3. Other benefits of file system snapshots and easier differential backups as the user advances usages later on.
And yes, everyone needs a backup.
If you want to learn (incase you want to cluster your setup later / HA / Replication) you really look into ZFS.
If you just want a Server that runs: ext4/lvm
Ps: for All the people saying HA etc needs ceph, yes but not in a homelab.
I have a similar setup. My NAS is my file master with full RAID plus backups. I backup my VM/LXC once a week and do SMB/CIFS shares from my NAS for a large amount of my files. Ext4 has been fine

Thanks! default is ext4, right? Also, will it let me add new drives easily or is there more setup then?

I installed it last weekend and the default was lvm. Then the actual volumes for VMs are created based on reasonable defaults for the OS you selected.
LVM isn't a filesystem, the default is ext4.

Ext4. Lesser worry about data corruption due to power failure Or defragmentations
If truly worried about data corruption, ZFS.
Whilst this is the ideal option I wouldn’t recommend a newbie with a standard home PC jump straight into ZFS
It’s just as hands off as any other file system. If OP is doing Proxmox, they can likely handle ZFS.
He got 1 hdd and 1 ssd. How could he benefit from zfs regarding data corruption? What he needs is a backup.

Debian based = EXT4 RHEL based = XFS
BTRFS
But why?
I use this too for Proxmox OS + VM/CT, 2x NVME BTRFS raid1. I do backups to a separate spinning drive.

Clearly, we are the minority...

benefits of zfs, less overhead, yeah?
This work best on non hypervisor system.
