You’re completely overthinking it. I keep white separate. Colors get their own basket. Denim goes in a separate piles after it really smells (it honestly shouldn’t be washed very much). Towels get their own load due to shedding. Sheets sometimes go in with the colors.
I do everything on cold. I use the plainest of plain detergent. If there’s a smell in polyester or nylon clothes I’ll put in some Clorox 2.
Dryer on low or medium until mostly dry. I’ve got a fancy one with a moisture sensor that actually works so I let that determine how long. Usually 25-30 minutes.

Proxmox can be a bit of a bear to setup. The documentation is not very approachable for new users. It uses a lot of terms without definition which is a deadly sin of technical writing IMO. Guides for getting an Ubuntu Server VM setup vary wildly and often recommend outdated settings.
I’m totally on board with using it though. It eliminates the need to start from scratch when migrating to newer hardware.
Set up your favorite Linux server distro and then go ham on setting up docker (dockge is a great tool to introduce compose).
