I bought a Breville with jogger knobs for power and time, just because I liked the UI. Most importantly they can be changed even while cooking.

I think this is the current revision: https://www.breville.com/us/en/products/microwaves/bmo850.ht...

It does have all the feature buttons, which are just inside the door, although I admit I have never used them.

Alternatively buy a really cheap microwave that just has two physical knobs.
