If I am understanding your intent correctly, you would like to use
Proxmox Virtual Environment (PVE) to host virtual machines (VMs). Using
the VMs as if directly working on (log into and using) each VM. This is
similar to remotely accessing workstations, servers, etc., on a network.

Though it may not be obvious, PVE is a virtual network environment with
the hosted VMs on this virtual network. In which case remotely accessing
the VMs on this virtual network is the same as on a physical network
with physical machines i.e., Some kind of remote desktop Viewer for
graphical user interface (GUI) and SSH for non-GUI access. The PVE
console for each or any VM can be used, however, this requires logging
into  the PVE web-GUI interface and working form there. This requires
giving all users access the PVE, not recommended.

SSH is install by default on Devuan and most GNU-Linux installation. For
MS Windows  Putty can be installed and used.
Windows RDP can be used to remotely access MS Windows machines, however,
Remmina, available on GNU-Linux machines, support multiple remote access
protocol including RDP, SFTP, SSH and VNC.

PVE can host VMs and LXC containers. For remote GUI (remote desktop)
access I recommend using VMs.
Using VMs for remote GUI access requires either passing-through a
physical graphics card from the PVE host, or using a virtualized
graphics card.

Passing-through a physical graphics card to a VM results in only that
one VM being able use that card. Therefore, a physical card is required
for each VM. This gets costly and is likely impractical.

Using virtualized graphics card is less costly and more practical.
However, VirtIO-GPU performs poorly. With PVE  I've found that the best
option is to use Spice/qxl combination. I have successfully used this
combination for sometime now without any noticeable latency.
In PVE set the VM disply to SPICE/qxl and install the qxl
drivers/modules in the VM. On GNU-linux install and use Remote Viewer
See the following Proxmox Spice web page for details:

Suggest reading the following pages:

Please note that PVE is built on Debian which means dealing with Systemd!
