Looking for bottle recommendations: "Four Ways to Build a Great White Wine" tasting

I'm putting together a white wine tasting for a group of friends (6-8 people). I'm WSET 3, but most of the group is enthusiastic beginners, so I'm trying to make it educational without turning it into a class.

The idea is that, instead of comparing grapes or countries (we've done that in the past), we'll compare four different dimensions of great white wine:

           Aromatics
               ↑
               │
Precision ─────┼───── Texture
               │
               ↓
              Age

Each wine should be a clear example of one of these four "archetypes":

1. Precision: tension, acidity, minerality, linearity.
2. Aromatic expression: a wine where the nose is the main event.
3. Texture: lees, body, mouthfeel, weight.
4. Time: a white that really shows the impact of age and/or has obvious depth and persistence.

I'm in Barcelona, so European wines are much easier (and usually much better value) than New World options. My target budget is around €30-50 per bottle, with maybe a little flexibility if it's worth it.

Right now I'm thinking something along these lines, ordered by preference:

• Precision: Chablis, Muscadet, Assyrtiko, maybe Etna Bianco.
• Aromatic: Dry German Riesling, Alsace Riesling, Grüner Veltliner.
• Texture: Godello, Chenin Blanc, Soave Classico, maybe white Burgundy (within budget).
• Time: This is where I'm least confident. Timorasso? Savennières? Viña Gravonia? An older Riesling? Etna Bianco? Something from Jura?

I'm less interested in finding the "best" bottle and more interested in finding wines that are really archetypal for each category and make the contrasts obvious for people who are just getting into wine.

What would you pick for each category?

Thank you!
