I’ve used ultra’s, 4000’s and 4 seasons on my k elites which are pretty much my stock training wheel; all go on fine in 23mm, never tried bigger. If you are anxious, the 4 seasons may offer you a bit more confidence, I doubt you would notice much difference in rolling.
Edit – as a chap who has had 2 lots of facial plastic surgery and 6k of dental work to restore my face to it’s former glory following a crash, i’d recommend not focusing on parts, just start where you can and build yourself back into it, it can take a while.
