Split resources for 3 VMs

I'm currently running a bunch of docker containers on my synology nas
but want to move 3 applications off to save resources.

I have an Intel DN2820FYKH NUC Mini PC N2830 2.41GHz 16GB RAM 128GB
SSD and want to run 3 VMs on it. Unless there's a better way?

Home assistant OS
Plex server (some light sharing with a max of 3 concurrent streams at
any one time, although that's exttreem and unlikely with possible
transcoding 720p and 1080p).
Pi-hole or alternative

I think I'm going to use Proxmax as my base OS but I'm wondering what
the best was to share my resources with the VMs would be? I definately
want a VM for home assistant as want to run OS but would the other 2
be better on a VM or docker? I've not used Proxmax before but I think
it runs docker?

Any hints or tips would be appreciated.

Proxmox doesn't 'run docker', Linux containers aren't docker
containers.

With that said, pihole and Plex run just fine in LXCs as does HASSOS
and this is exactly how they run in my home lab

Okay cool. I've learned something already. So you're saying I can run
all 3 in LXCs rather than VMs and that would fine? Do I need to assign
resources to them or does that all happen on the fly?

HomeAssistant is a VM template or docker image (which you could run in
an LXC, but i would just run the VM). The other two you can just run
in LXCs, LXC resource allocation is functionally the same as VM but
its way faster and more flexible - LXCs dont need a reboot if you
adjust RAM/CPU allocations, and they can consume more than you give
them if the host has capacity available.

If you want to easy-mode your way through the setup, here is a helpful
repo of scripts that can configure both LXCs, the VM, and other stuff
