I’m back to ambulatory but I used a few during my problem.
Unless you’ll be using the walker outside I’d stick with the stand up version, the one without the seat. They go for about $20/30 on Amazon as opposeed to the wheeled versions with a seat that go for about $50/100. Plus until you practice with the brakes on the wheeled version they can get away from you. One with two wheels in front should be ok but you may need a physical therapy pro to fit it to you. That’s important to avoid back pain or other problems. You can put skis or tennis balls on the rear. You can add a basket to carry food for about another $10.
Here’s hoping for your improved mobility.
