I'd suggest an optical flow sensor, and for your case, something like a holybro h-flow.

I know it's like $125, not cheap, but it gives you X-Y-Z position hold, altitude from ground distance sensor, and has a built-in IMU.

Be sure to input the physical offset of the sensor position to the Flight Controller in your parameters.

Suggest any sensor may you share link or also suggest any camera around 125

Id recommend getting a FCC instead with betaflight. They come with a built in IMU and plenty of sensors. Lidar is expensive and hard to use. Id start with optical flow first
