Usually I desk check to consider the Aperture I'll use considering my expectation of the scene. I use Photopills app on my phone. You may use this web version.
As an example I wanted to that light trails of lighted Disc Golf. I wanted to use my 12mm f/2.0 lens. Since there is no way I could focus on the dark what could I do?
I used Photopills DoF and setup my camera type. f/2.0 then estimated the subject distance to the camera of 50 ft.
That didn't work since the near distance was 49.+ ft. So what if the lighted Disc lands say 10ft from my camera? Using a subject of 20 feet gives me a near Dof about 9ft and a far of infinity.
The result yes but some of the discs landed out of the Depth of field in front so they are not sharp.
To me it's all about "acceptable" sharpness.
UPDATE(20241126) - Hyperfocal distance
Of course YMMV.
