Have a look at this application note from Texas Instruments:
https://www.electro-tech-online.com/custompdfs/2011/10/sloa087-1.pdf
It covers several different sine wave oscillators with discussions of strengths/weaknesses of the circuits, and formulas to assist you in calculating components to get your desired output frequency.
Consider the quadrature oscillator on pages 15-19 to 15-20; it's pretty simple, will start quickly and has both sine and cos outputs.
