For halyards you'd go with the smallest diameter. I see 6mm listed, which is already more than you need. Dinghy Control would also work, I've owned 15' dinghy that was rigged with 3mm for the halyards, but even for the DS you might never need more than 4mm.
For sheets that you might hold in your hand for extended periods, you'd base your diameter on what is comfortable to hold, but for halyards that's less of a consideration and cost and weight savings dominate the calculation.
You might like to look at their Line Selection Guide. One key parameter is the stretch: for halyards the lowest stretch is a must. The other is the strength. I don't think any line on a DS will ever be loaded over 1000#, or even 500#. So you can see most lines are overdimensioned and you can safely go to smaller diameters than the standard recommendations for the DS.
Speaking of recommendations: if you don't have a working example of a line, order a bit more rope than you think you need and cut the line down to length after rigging.
