Home Assistant Yellow - What to Expect When You're Configuring

So my Home Assistant Blue suffered a tragedy last year and I temporarily switched to using a Pi 4. Then Ameridroid had the Yellow (PoE!) available, and here I am with a Yellow, waiting for the CM4 ( CM4108032) and SSD to arrive tomorrow, and realizing I have no idea what to expect or if there is anything I should expect when I start the config and move this weekend.

Background: I’ve run HA for roughly four years now on Pi4, Odroid, and in Docker on my server, but since moving it to the Pi while waiting for the Yellow to come in stock, I’ve only done basic maintenance and working on other projects, so on a guess, I’m going to have to brush up my python and yaml. And anything that’s changed that I may have missed.

This will be a scratch initial installation; after linking up my integrations and getting my naming conventions consistent, I’ll start copying my yaml files and code over and decide how much of my interface I want to keep.

Any advice would be appreciated if there’s anything that’s very different with the Yellow hardware. I use two SmartThings Hubs for zigbee, zwave, and matter over Thread control for the most part but have been dipping my toes into direct zigbee control (just not that well yet) and trying to get direct matter over thread to work (not going well at all). And do I need my skynet dongle or Sonoff zigbee dongle or will the built in module work across the board?
