Paranoid Linux distro recomendation

Hi all, I'm about to set a 2/3 multisig. I bought a brand new laptop to act as a coordinator. I still don't know if I'll use Sparrow for a normal multisig or Liana for a multisig + timelocks. I'll use the laptop exclusively for this. It will have its own pruned node.

I ask you, which Linux distro do you recommend? I know I don't need to get too paranoid, the keys would be in the HW, but I want to protect the XPub and descriptors almost as if they were private keys.

I have read about QubeOS, but the added complexity isn't worth it, given that I won't use the laptop for other things. I have also read a bit about Debían + Kicksecure, Fedora Silver blue and openSUSE, but don't really know which one would be better.

Thanks in advance!
