capital gain tax - self assessment

My total gain for the tax year 2023/2024 is below the £6,000 capital gains allowance, but I sold shares with a value exceeding £50,000. Do I still have to do tax self assessment due to the value of proceeds? Is it actually £50000 or 4 times annual capital gain allowance (4x£6000=£24000)? Also during the same tax year I earned £3000 form my saving account which was not an isa account. Does £1000 allowance applies and I have to pay tax only from £2000, is it another reason why I need to do tax self assessment?
