Rob, I'll give you my threppence worth, but it has the usual caveat that taste perceptions vary between people, so don't blame me if you disagree
First, what to absolutely avoid... In my experience the white wine that splits drinkers the most is Chardonnay, when matured in oak barrels. This can put lots of strong woody flavours in but, more importantly, usually leads to malolactic fermentation which converts malic acid to lactic acid (the name gave it away). This creates a less zingy, slightly sweeter taste and a rich, buttery mouth feel. Chardonnay is not usually light. Unoaked examples are relatively rare but do not have this richness and I'm a big fan.
Next, a maybe. Sauvignon Blanc is another option, but care is needed to get the lighter ones. At one end of the spectrum are the New Zealand SBs which are very shouty with strong tropical fruit flavours. They can't be described as light but are certainly fruity. They can stamp on food flavours. The other end is French SBs which are lighter, have more citrus and green apple than tropical flavours, and usually have a much nicer mineral finish. This ticks the refreshing box. In between are SBs from South Africa and South America, which can lean either way and would need some testing on your part
Third, another that sprang to mind because you said Pasta is Vermentino from Sardinia or the west side of the Italian mainland. If you can find the right one it will work perfectly. Again, though, they vary from quite light to quite rich. A lighter one would be fruity and a bit sherberty and very refreshing. Needs research.
Now, a mixture of great suggestions. Albarino from Spain and French Picpoul de Pinet both fit the bill perfectly, especially with fish or seafood dishes. They are great value, light and refreshing and usually fruity. A Greek Assyrtiko would also be a great choice, but they are a bit more expensive. A Riesling or Gruner Veltiner could work but there is a wide range of quality. Avoid Gewurztraminer because they stamp and shout.
Finally, a pair of curve ball suggestions. Try a Portugese Vinho Verde, which are a bit lower in alcohol (lighter) and have a really gentle sparkle (refreshing) with green apple flavours. Great in Summer and good value. A Swiss Chasselas, dry and light, and definitely fruity.
TLDR: avoid Chardonnay and stay in Europe.
