Where are you getting that temperature from?
Just checked the other bag mentioned and its rated at -7 according to WM website.

But you haven't got one like that. If you are going to be carrying a tent on the back of a bike for just the one of you, may it's time to invest in a decent light tent. My Hilleberg Nallo 2 got a huge amount of use.
The sleeping bag is your call, because only you know what weight of sleeping bag is adequate for you in different temperatures. I think the condensation point is not a real issue. I've cycle-camped a lot in Iceland and the high Andes etc, and yes occasionally you do get some heavy condensation inside the tent adn dripping on you, but it has never affected the sleeping bag badly. A useful trick to learn is the space-blanket. Only weighs 60g, can be refolded back into its packet and repeatedly re-used: it adds a season to a sleeping back and protects it from dripping condensation, in the rare event that becomes a problem. It can also be used to lay out over the groundsheet for added ground protection if you don't need it on top of you. I'd rather have a sleeping bag on the light side than on the heavy side, because over-weight sleeping bags are a nuisance, I've become completely sodden in them by sweating, and if you have the zip open you get cold patches. But if the bag is on the light side, you can use the space blanket and put some clothes on if it gets cold, to provide variability over a wide range of conditions. Thus I have camped at -20C in a 3-season bag.
The thing about the weather in Iceland is that you hope for the best and prepare for the worst. Yes, I've cycled most days in shorts in Iceland in summer, but I've also had some pretty cold and savage weather. I've had a light frost even in July, and that by the coast. A few days earlier (still July) it was 4C at lunchtime and raining at sea-level, and later I could see that there was a scattering of fresh snow on the hills above about 500m.
On another trip, this time mid to late August, we had some quite wild weather here and there - two storms, and heavy snow that fortunately fell where we'd just left, not on us. We camped at the Dreki Hut at Askja when there was a storm. You really had to hang onto your equipment - I saw someone's sleeping mat fly off high into the air never to be seen again. The pre-pitched tents used for tour groups were completely destroyed, though fortunately not occupied that day. My Hilleberg Nallo 2 survived and we slept in it, though only 2 other groups of campers managed to stay in their tents. At least we had a hut that day, we'd made a very remote crossing of the centre to get there. A couple of days later, at Myvatn, we had quite a heavy frost. The day after we left Myvatn, we heard that they had heavy snow there, and most of the campers there had to be taken indoors. The road to Askja was closed, and people at Askja and Herdubreidarlindir had to be rescued. I was rather worried for a cyclist we met cycling in to Askja as we were leaving - he would have been beyond Askja in the deep interior by then. We had to sit out a day in our tent for this second storm. But he was a very experienced wilderness cyclist, told us he had cycled on Lake Baikal in winter. There have been "surprisingly early" heavy snows in so many of the recent autumns in Iceland that it is ceasing to be surprising.

In Iceland people mostly live in places with specially favoured micro-climates like Akureyri, and these are the places for which such data is available. The wind data is especially misleading, it is in a steep-sided fjord located N to S, so it is perhaps unsurprising the wind there is mostly N & S.
Even without visiting anywhere unusually remote, the cyclist will have to deal with a wider range of weather than that suggests.

Sleeping bag-wise, use the lighter option. A water resistant outer is nice, but not enough to warrant getting all sweaty in an over-warm bag. Condensation inside the Nallo is unlikely, so the main risk would be a kicked pan or drips off a waterproof jacket, both of which should be easily avoidable in a tent the size of a Nallo 4 GT.
I'd use my PHD Minim 300 with a silk liner. It's OK down to zero, and unzips to use as a quilt with my feet as a radiator if it's on the warm side.
