SSD and file system

I just got a Dell Optiplex 7050 with 7th gen Intel I5 and 500 GB SATA hdd.
Will add 4x16 GB RAM and a 2TB SSD.

Plan to use this for some Docker/LXC for development/testing and VMs for Plex, GitHub runner, as well as various Unix and Windows VMs(on demand for development and testing). Though the GitHub runner, Plex VMs and couple of Unix/Windows etc. will be running at the same time, I don't think there will be any serious load or activity on any of those especially all at once.

I don't care about mirroring data in real-time and this is not a mission critical system.
But would like a way to backup the VMs on a periodic basis though (likely daily to an external storage (or another HDD/SSD if need be). What is the best way to do it?

Considering the use case, do I need to use ZFS at all? Asking because if non ZFS can extend the SSD life, I would like to. Also, any recommendation between Intel 620P vs Samsung 870 for the 2 TB SSD?
The HDD looks fine for Proxmox itself and some storage like ISO and maybe a place for one copy of your backups.
You don't need to use ZFS at all if you don't want to or requires its features.
Try to get an (second-hand) enterprise SSD with PLP for running your VMs and CTs, or at the very least make sure to not use a QLC SSD (even without ZFS).
Please note that there are many threads on this forum about problems with Docker in a container and Proxmox advise is to use a VM for Docker.
