Moving a Bunch of Docker Images to Proxmox

I'm running Ubuntu on an aging Mac Mini that I want to port to new hardware before it fails on me. I came across a video on iKookCore R2 configured to run Proxmox. That got me looking into Proxmox.

My Unbuntu image primarily supports my home automation apps along with a few others. I have the following docker images: portainer, esphome, home assistant, mosquitto, grafana, frigate, influxDB, node-red, and plex. I'm also running postgreSQL, Adguard, nginx, and gunicorn directly installed to the OS. There may be one or two I've forgotten. I'm also considering Opensense and Nextcloud.

I'm interested in using containers and VM's in place of Docker as they appear to have some advantages. Are the number of apps I'm running going to cause a lot more overhead than running them all in Docker? Would any of these better better off in VM's as opposed to containers? I rarely use Plex and the others are low CPU users.

I'm looking to get the iKoolCore R2 i3-N300 with 16GB of memory and a 1 TB SSD. They're sold out at the moment so I may look for something else. I like the lower power aspect of them.

I haven't used VM's since I ran them with TPF on IBM mainframes. It should be fun to get back into them.
