I run proxmox on an i7 10700 8c/16t CPU. I have this idea that if I have a gaming VM, I shouldn't over-provision cores and even leave 2 for the host, but is that really the case. Can I somehow ensure VM is basically pinned to say half the cores, and the other half can be fought over by whatever other VMs I'm running and proxmox itself? Could this affect performance on the gaming VM?
What are you trying to achieve? I could propose alternatives like using a password manager like bitwarden that would autocomplete login info so login is less of a hassle. You can also use SSH to start/stop/list/etc. VMs so you could create a small local UI or shell script to automate the tasks using key based auth so you don't have to input login data.
I also don't think there's any reason for your proxmox web UI to be available outside your local lan or a VPN. Maybe I'm misunderstanding the question.
