I don’t have massive experience but about 25 years ago I purchased a unit using transistors to power large stepper motors (probably a similar style of load to a solenoid - inductive with quick on/off) and it worked well, and didn’t get too hot. But don’t ask me what transistor tech it used, or the name of the company selling it! But if you don’t need the response time or longivity then relays are probably much simpler to set up so a good choice.
