I want to do the same to free up a ‘stretch’ of bench space, rather than having only small work areas in the corner and ends of our small L shape. I am talking stove top only as oven will be in a tower with microwave. That means the cupboard underneath can utilise the whole space, albeit with relatively small door (430mm). We would have to offset the range hood on the adjacent wall due to window position but have been advised the modern hoods are powerful enough to extract steam without necessarily being positioned absolutely over the hot plates.

Need to change my oven after having had a lousy Arda brand that has given me grief for the last 6 year. What’s the best induction stove to buy in medium price range

If you install a cooktop and then an under bench oven or a wall oven, this gives more design capabilities than just a freestanding combined cooktop and oven. With separate appliances your not restricted in your kitchen design. Wall ovens are better ergonomically.

I think your kitchen is lovely and I wonder if black would look somehow too heavy? Stainless has been around for a while and continues to be popular and your other appliances are stainless. Rangehood too, I'm not sure about a black stove under a stainless rangehood. If there's a trend for black now and you're not really loving it and you're not planning to change other things to coordinate with it, I think stainless is just fine.
