This is probably wrong, but here's a breakdown of main (team name level) sponsors at World Tour level
Most popular is the construction industry with 6 sponsors: Bora (Kitchens), Wanty (civil engineers), Deceuninck (Windows), Soudal (adhesives and gloopy stuff), Hansgrohe (bathrooms), Quick-Step (flooring)
Then we have 4 sponsors that are places. None of which I have an urge to visit. Astana, UAE, Bahrain, AlUla (Saudi Resort)
Four from Finance/Insurance: Cofidis, Arkea, AG2R, Groupama
Three from the automotive industry: Jayco, Citroen, Grenadiers
Two each from gambling and supermarkets:
Gambling: FDJ (lottery), Circus (online gambling)
Supermarket: Jumbo, Intermarche
That leaves one each from the remainder:
Bicycles (Trek)
Coffee (Segafredo)
Education (EF Education)
Facilities management (Samsic)
Nutrition (DSM)
Petrochemicals (Ineos)
Shampoo (Alpecin)
Shipping (Easypost)
Software (Visma)
Telco (Movistar)
Airline (Emirates) added on advice from

You might want to point out errors, or argue with classifications - eg are Soudal and Alpecin both actually petrochemicals?. Feel free to do your own breakdown.
So which cyclist has best represented their sponsor?
I'm going for Marcel Kittel and his splendid Alpecin quiff
