Wide-angle photos have a confusing number of lines.

Which one should be used for straightening the image?

One in the very center perhaps?

When I have several lines, I pick the one I that I feel should be
straight, of course that may vary with the image. I your camera and lens
is listed, The ACR filter has a setting for automatic adjustment. As
nospam suggested, You can also use the WA adjustment tool in PS.

The same can be done in Lightroom Classic CC.

It all depends on what you want to do.

Always, but it is a good idea to know how to use your available tools. The
straighten tool is not always the best tool for the job especially when
shooting wide & ultra-wide, for architecture and other shots where there are
multiple vertical lines.
