Figure 9.1: BJT nonlinearity. This relationship between base and collector currents is called the current gain, and for AC operation is given the term h fe, and its nonlinearity is an obvious source of distortion when the device is used as an amplifier.Alternatively, one could regard this lack of linearity as a change of h FE (this term is used to define the DC or LF …

Voltage amplifier amplifies the voltage and the power amplifier boosts up the power at the output. A voltage amplifier should have higher input impedance and lower output impedance. CE mode BJT amplifier is a voltage and power amplifier. CC mode BJT amplifier is an example of current amplifier. These are the classification of power amplifiers.
Power amp output - BJT or MosFET? | diyAudio
https://www.diyaudio.com/community/threads/power-amp-output-bjt-or-mosfet.32634/
impedance loads in terms of power output is very mundane compared to BJT's. IMO most MosFet "simple" designs are far too simple and BJT's would in most of these cases provide better overall performance. I have a hard time seeing the justification for MosFets as a good solution for "standard" class aB amplifiers, i.e. most amplifiers. sreten

bipolar (bjt) transistor families for audio power output stages. …. there are many technologies by manufacture to reach perfect data so as high linearity and transit frequency. The newest is "BiT-LA" (ST) and older versions are "M.E.T" (TOS), "LAPT" (Sanken), RET (FUJ) and EBT (NEC). I think, there are many more versions without especially ...
