RAID array filesystem recommendations (sopuli.xyz)

I am planning on creating a home server with either 2 (RAID1) or 3 (RAID5) HDDs as bulk storage and 1 SSD as bcache.

The question is, what file system should I use for the HDDs? I am thinking of ext4 or xfs, as I heard btrfs is not recommended for my use case for some reason.

Do you all have some advice to give on what file system to use, as well as some other tips?

ZFS doesn't require a lot of RAM, but it will use more RAM if it's available. 32G would be plenty for a home setup. I think my home file server has 24 or 32G of RAM and ZFS. If it's important data then stick to what you know; there's nothing wrong with mdadm.
