Opinions on when to merge multiple LXC into a single VM (or not)

I have been loving Proxmox now for several months (as my home lab et al) and virtualize most everything at this point.

One dilemma I'm having now is at what point, or not, do I merge multiple LXC to a single VM.

For example. I run Plex, Tautulli, Sonarr, Prowlarr as separate LXCs (possibly more like Radarr or Lidarr or other realted services even). Each now have their own IP and ports. Each have some RAM, CPU and HD dedicated to them. They're all mounting a remote network share to play/record the shows/movies. I *think* the Plex LXC does some magic to get the GPU for transcoding as it shows up in the Plex menu, so that part isn't really a concern (or benefit of having a VM version where I could dedicate some GPU to it that way).

I'm wondering if setting up a new VM and installing all three on there (as native apps, not dockers) would be more efficient and save resources (not that I'm really worried I have a dual xenon with 72 processors and 128 GB RAM), but tying up 3 IPs is kind of sub-optimal. 3 Separate services might be good or bad depending on how you view it (decoupling services and all that).

Just looking for thoughts/ideas/concerns/encouragement and what other folks do or don't do in this situation.
