i like your discussion.

I am an inexperienced user who needs to remove backgrounds from race cars for our foundation fundraiser event posters. We raise money for kids fighting cancer. I have a macos Catalina vs 10.15.7. Am frustrated that I cannot seem to master the tools in photoshop to do the car edges well. I feel like I would have better control using a pen or stylus, but I know nothing about these either. Would appreciate your help. Thank you.

There are many good tutorials on the web for learning how to use Photoshop.   I have  a few hint that may help.   You do not want to use the new trace pen tool.  I do not know why Adobe  even release it.   For best results you want to create paths that have the fewest amount of control points as possible. To start with it is often easier to start by quickly drawing out straight line path around an a object with the pen tool then switch to the curvature pen tool  to edit the  the crude path you created around the object.  Learn how you can edit control points with the vector tools. Add move delete convert adjust them. Paths are easy to edit once you know how to. Closed path can be combine several ways learn how  you set and change the way paths combine, to make the shapes you want.  Learn how to use Photoshop's vector tools it well worth the effort.

Best is to use the pen tool for selection if you want to achieve a perfect selection. Use the pen tool as a path and convert to Selection. I will also go with the select and mask and see where you have mistakes.

For selections with hard solid edges the best tool is the pen tool. Use it to create a path around the car, then make a vector mask from that path.

The pen tool can seem a little tricky to learn at first, but it is well worth the practice as nothing makes a crisp selection quite like it. https://helpx.adobe.com/uk/photoshop/using/drawing-pen-tools.html

Note - the pen tool is a Photoshop tool and has nothing to do with a pen and stylus and I actually find it easier to create pen paths with a mouse.
