There's a super big problem here, and that is, VERY FEW strollers have a reversible seat unit while weighing under 8 kg. That is super super rare and hard to find many examples just so - and to add a large hood to the requirements, it makes the choice almost impossible.
We just got a Cybex Melio review - check all the Cybex Melio reviews on the strollers page, there are a few (mixed positive and negative) - but overall, when in the reclined position, this won't be a pushchair with a large hood. I had the Cybex Mios which is a similar stroller, and it was a nice one, BUT not one with a large canopy when laying flat. We used a sun shade in the summer, and that is what I recommend considering to you as well - I mean, it is a simple thing to put on and it will solve most of your problems.
My other stroller suggestion would be the Easywalker Charley - it's also a lightweight, compact stroller and the hood is larger. To get the idea, read our
- there are quite a few pictures to illustrate. It's a sturdier pushchair, so it will last better, but the Charley seat is a bit shorter, compared to the Cybex's. The Cybex strollers, on the other hand, DO have a narrower seat (but I could fit a 4-year-old inside, so it works if you don't need something super-wide). The Charley's seat is wider. And a 3yo was OK in it, even if maybe at the end of the stroller's use.
Anyhow, I suggest strongly only setting one main priority when choosing a stroller, it will be much easier to accept the downsides of the chosen model. I mean, no stroller is perfect, and some features are very hard to put together (and if, it makes the stroller heavy/bulky/...).
