I’ve used 3 pin sections of 0.1" headers for a SOT-23. You can solder two pins directly to the header, and use a short wire for the third pin.
I’ve also made my own breadboard friendly parts such as a LM7805 solered to a 2x3 header for more mechanical stability and a small heatsink already attached.
When working with TO-220 MOSfets on breadboards it’s a good idea to add small TVS diodes directly between the gate and source.
I have used breadboards quite a lot, but I have never liked the pictures of breadboards with the colored wires. Those wires do not mean anything to me, and you do not learn anything from those pictures. You can’t even see whether those wires are correct. On the other hand, some circuit is quite easy to build on a breadboard if you have the schematic. The schematic also gives meaning to what a circuit does and how things are connected.
But overall, things are more going in the direction shown below, and that is indeed not going to play well on a breadboard.
