Input 24V, output 8Ω/5W. Regardless of the sound quality, distortion and other issues, I searched the Internet and found that similar circuits can be implemented? Can it be 3W? A triode directly?

3w is not good. The maximum Ic flow of 8050 is 0.5A. It depends on the amplitude of the input signal. It can reach 5w by changing the tube and adjusting the circuit parameters.

S8050 maximum current is 1.5A

Class A power amplifier, achieve 5W, 8050 package is TO92, you may need dozens of them in parallel, then, design parameters so that the collector voltage of all 8050 is half of the power supply, the total static power consumption is greater than 10W, the output capacitor capacity considers low frequency If you need to increase it to the level of Qianweifa. If you find it troublesome, you can consider the power amplifier chip mode, there are many.
