I have an Arc Ultra sound bar and I'm thinking about In-wall speakers for the rear. I have power available, so can I go without the amp and just connect them to my Arc Ultra through WiFi?

If you do not want actual speakers on stands for surrounds, if you can find IKEA picture frame speakers, this could be a good solution. Other wise as ​@Airgetlam has stated, you will need an Amp to connect intaglio speakers with the Arc Ultra:

No. The Arc doesn’t have an amplifier to drive rear speakers. It does send a signal, but it needs to be ‘received’ by the Amp, which powers the rear speakers.
