If your solutions are work/job related and need to be distributed I think your current options are SUSE or Debian. If your solution is something only you maintain, you could check out NixOS.
One of my work colleagues actually uses Nix on Debian to distribute a piece of software. Though it is software made for a hardware appliance so that's a bit special.
Honestly, unless you're using Nix within something like docker images (Nix has great support for writing really minimal docker images) or use it to just build software (which is also a great use-case), I would rather go straight to NixOS, in my experience it's a smoother experience than using Nix on a different distro and e.g. services (like standalone home-manager) .
