For lighting, I would personally avoid smart bulbs, especially if you are redoing the apartment anyway.
All they lead to from my experience are annoyances when guests/partners inevitably flick a switch and turn off the smart bulb.
I live in Australia so the spec may be different from where you are, but I have found ZigBee to work amazingly.
The witness is a really interesting puzzle game that can be had for not that much.
Or if you are looking for something more actiony then I would recommend remnant: from the ashes or remnant 2. Described as souls like with guns, but they really change up the formula I found with semi random worlds and bosses.
