Ooo, can’t wait to try this out!

What do people use who run an M1/M2 based Mac but want to run an x86 VM?

Because you can't do this with Virtualbox.

UTM. It's qemu under the hood and will emulate x86 if you want it to. (Or other architectures, it runs Mac OS 9 under an emulated PowerPC perfectly. Great fun.)

But it's not quick. I would not attempt to run a modern Windows on it, I don't think it would work due to a lack of performance.

For those not familiar with UTM:

"Securely run operating systems on your Mac"

$10 for a GUI.

It's both free and open source (https://github.com/utmapp/UTM). You can pay 10$ to get automatic updates, which IMHO is a very fair price and you are helping support the project.
