So I am partially doing the chosen design because I got the ICs "for free" along with the tubes and because this is my first electronics project. I don't have much experience or equipment yet and so I don't think attempting something like a flyback converter would be a suitable undertaking for me.
So I still need to find a pre-built solution, unfortunately... Also: I came across this site: https://www.nixieclock.org/ is that literally just a rip-off of https://omnixie.com/ ???
