An object is placed far away from all the objects that can exert force on it. A frame of reference is constructed by taking the origin and axes fixed in this object. Will the frame be necessarily inertial?

If the object is absolutely free from external forces, it's acceleration must be zero. So the frame of reference fixed in it must be an absolute frame of reference where Newton's laws of motion hold good. Thus it is necessarily an inertial frame of reference.

Yes the frame will be inertial, as an inertial frame is a frame where newton’s first law is valid. Hence in this object net force = 0 and also the accelaraion of this object in the constructed frame is zero, therefore first law is valid and frame is inertial.
