Yes. Make sure both source and destination are the same macOS version. I use 27.0.1, you could upgrade to 27.2 first though.

Then do a fresh install on your new system and then use Migration Assistant. Use a USB-4 or a Thunderbolt cable to speed it up.

yes, if your plugged into the Apple Ecosystem, upgrading to a new machine is a breeze, done it many times

I'm in the exact same boat as you, exact same specs. CPU/GPU holding up perfectly for my use cases, but 512GB is tough to manage now.
