New circuit for wall oven

I need to run a new electrical circuit for a new wall oven that will be installed in our kitchen in several weeks. Between the oven's specs and this wire size calculator it appears that what I need is a 30 amp circuit with 10/3 cable. The length of the circuit will be around 20-30 feet. Hoping someone can confirm the 30amp & 10/3 details for me. Also, I don't see on the specs page or in the manuals what type of plug it uses; would this level of electrical usage still use a standard plug?

10/3 wire is good for 30 amps at 25 feet. Most likely the oven will be direct wire and not need a plug.
No the plug if needed will not be standard. If I remember correctly the blades on the plug will be slanted toward the outside edge as viewed with the ground prong at bottom. Round ground pin at center bottom and other blades tilted out on either side of it. Google 30 amp 120 volt plug to see examples.

Most wall ovens come with a flying lead and are hardwired to a junction box.
No cord or plug supplied.

Is there some way I can use a 1-pole breaker with 10/3 cable? Guessing not, thinking I overlooked this earlier, but hoping I'm wrong. It's going to get a lot more difficult if I need a 2-pole breaker.

One pole breaker will only give you 120 volts. You need a double pole (not a mini or tandem) to get 240 volts.

Why would you need 10-3 at all, the oven only requires 240 volts. 10-2 should work just fine. I believe I'd wait till I had the actual oven in front of me before installing the circuit. I've seen appliances before that had specifications that said the appliance was 240 volt, but what was provided from the factory was a 4-wire whip for a 4-wire 120/240 volt circuit.

A link was posted in the first post that is for the GE unit the OP is getting. Its 240v and 30A.
That means a 2P breaker is needed and I'd run 10-3 instead of 10-2 for future requirement.

Thank you, all! I did go with 10/3, and I figured out how to open up another breaker slot, so I think it's going to all work out. I have the cable run from the oven location to the vicinity of the breaker box, now just waiting for a good time to shut off power to the box so I can wire it into the box with lower odds of shocking myself in the process. I have a 30-amp 2-pole breaker I'll be using.
