What smart bulb to choose in a chandelier?

Question

Smart House

Hey!
The idea is to combine a light alarm clock and a chandelier. The requirements are as follows:
-setting the color gamut
-setting the brightness range
-possibility of control from the phone via google assistant
-support for scenarios: it will turn on in time and gradually increase the brightness from x to y over time t
Please advise what to choose. I read several times about xiaomi bulbs, but many people mention that they cannot be integrated into the mihome Chinese region, and the scripts in googlehome are too primitive.
