Just simple square/rectangular stock whereby I can find the XYZ as efficiently as possible.
I have found one (plug and play) that I can wire into the machine. that just plugs in via a Molex terminal and is not too expensive (well not for me as Santa will duly be informed)
Its only small and not on the scale that would be needed for 8'x4' machining.
I was just wondering if it's worth investing. Looking at it after installing and setting up the macros it seemed like a good idea.
Then again I'm only a newbie

For XY I have a small laser mounted. That is for "rough" positioning because the dot is fairly large. I use that when I am cutting something completely out of a piece or accuracy is not important for XY zero. It is a cheapie laser that was intended to be used on a pistol for a laser sight. Cost about $30 IIRC. On my engraving laser I do not have power control so that cannot be used but would be much better. Maybe one of these days but I hate fooling with the wiring, just not my thing.
One thing that has really helped is Ger21's Screenset. I run the Mach3 version but he has versions for other controllers. It makes setting up a touch off plate very simple. Connect to the proper input and a few simple settings in his macros. Plus it does a ton of other things. Like a Park position button which can also be called from the g code. And his screens are not ugly like Mach3's! LOL.
Does Ger21 make a custom screen set for WinCNC? If so, where can I purchase it? I could write my own but if he has one that is similar to what I'm looking for why re-invent the wheel.

This allows me to locate material edges, holes in material, features I wish to avoid etc.
It's very accurate and fast to find my reference points. Then I use a Z touch off plate to set the Z height.
Not sure what control system you have, but I use Mach3 and Klaus's video plugin. https://kd-dietz.com/pages/eng/plugins/webcamv3/changelog/wcam_changelogv3.html
Just thought I'd mention it.
