There is no problem at all with waterproofing a landscaped roof so long as you don't 'cut corners'. The problem arises if there are not adequate standards set for the supply of the product and the installation of the product. With the use of superior water proof membranes and installation by specialists there is no issue at all. This sort of roof is used all around the world.

You can get slim range hoods that generally fit into the wall cabinets ours were approx 40cm deep which housed the complete operation, our plumber ran a 6 or so inch flexable ducting into the roof cavity and out under the eaves. Most brands make these. A photo would be helpful. https://www.thegoodguys.com.au/omega-52cm-undermount-rangehood-oru50x?CAWELAID=620013790000422290&CAGPSPN=pla&CAAGID=21711678566&CATCI=pla-376401441757&gclid=CjwKCAjw0qLOBRBUEiwAMG5xMNN63iJr0n0Bnxf31-Gt0t5s0vERt_lOwOYkC6uzovf9TDWwawry9RoCgxQQAvD_BwE&gclsrc=aw.ds&dclid=CLOv9erawdYCFc0slgodE5oLHg Where we didn't have wall cabinets we had tall boxes of stainless look laminate built up to the ceiling which contained the extraction unit, which was approx 30-40cm's and extraction ducting cheers

Option 3 as you don't lose any valuable floor space. The top of the new stair could have a skylight above, or windows to the side to bring more light into the centre of the home. Just make sure you have a light, open stair design, with open risers, and a see-through balustrade. You will need to pay attention to how the new stairwell penetrates the existing roof structure to make sure the roof deck drains correctly. It has the potential to be a glorious (and expensive ) feature to your home. Remember that God is in the details. Best of luck, Dr Retro of Dr Retro House Calls/Dr Retro Virtual Visits
