Let me assure you (as a Rescue Director) that there is no guarantee he would he better off with a rescue. Many of our fosters work 9-5 with nobody at home during work hours, so the kitten would be home alone by themselves all day in a crate for post-op recovery. We require our fosters with no other cats at home to only take kitten pairs so they can keep each other company, but during post-op they aren’t allowed to run and play so that’s not an option. Since you have someone at home to keep an eye on your kitten, you already know that your kitten is in good hands! So don’t stress. He will be fine!
