I wouldn’t recommend a tube amp to a beginner. There are too many good modelers out there that will teach you which types of amps work best with the music you play and the way you play it. Once you think you’ve passed the beginner stage, you’ll then be able to better appreciate which each type of tube amp offers you.
I say look at the Boss Nextone Stage. Wanting your first amp to be tubes “because toobz!” can be counterproductive.
I wouldn't recommend a modeling amp to a beginner. Too many options can hinder its use. Especially by someone who isn't familiar with all of those options and how they work, etc... It's WAYYYYYY simpler to adjust a couple of knobs on a tube amp.
Wanting your first amp to be a modeler "because you don't have a clue about types of tube Amps, effects, etc..." will be counterproductive.
What your saying isn't logical in the slightest. Why start a beginner out on an amp thats 200x more complicated than 99% of tube amps?
In fact, it doesn't even have to BE a tube amp. It could be a solid state whatever. A Champ 40 or something. Just not a modeler. Why start someone out on a Helix or Axe Fx, etc...when a simple amp with a few controls would suffice?
