Folders

I have two different workflows- one at work and one at home.

For work, I almost never have images coming off a memory card. I shoot products with a tethered camera, process in Bridge/Camera RAW, and move to my production workstation. My folders are organized by product type. Filenames are overloaded to use the product part number. Dates are mostly irrelevant, that data is stored in a spreadsheet (ad hoc flat file database.) Metadata is king here, I extensively keyword, and I have numerous scripts to manipulate metadata. Searchability is huge.

For my freelance hobby/business at home, I use Lightroom (RIP Aperture) and copy images from memory card to folders using the Finder and card reader. I organize RAW files by date (year folders, then each individual shoot by date.) Finished photos are organized by location for landscape/travel work, subject name for models and portrait clients, and job indentifier for client work. I don't use keywords and just find things by location or name. Searching isn't very important.

You can either copy newly taken images images into the computer yourself, in the course of that manually creating and directing picture files (camera JPGs or camera Raw) into whatever folders and subfolders you think best - or else you can have Lightroom Classic take over the task for you and save yourself a lot of that work.

If working manually, you can implement whatever folder scheme you want but must then micromanage which photos go into what folder. After that you still have a further separate operation to identify which of those folders should or should not have their contents brought into the LrC Catalog's image library, and then use an "ADD" import which keeps everything where you've put it without any subsequent moving or copying.

For LrC to take over the task, depends on using some consistent import folder scheme which LrC can implement all by itself, such as most commonly an auto capture date based scheme.

This is what I have done for many years: a designated location on disk contains Year subfolders, inside each Month subfolders, inside each Day folders, each that has been created automatically as required, and then each incoming photo is automatically filed under the appropriate Year and Month and Day. So I see one consistent dated folder structure inside the Catalog which LrC has accumulated over many years. This has happend.with zero input from me except telling LrC to Copy and Import new photos off the card reader when needed. No settings were individualised by me each time, except for batch keywording. That has been the long and the short of my file and folder management.during all this time.

Consequence: automatically filed images are not going to be characterised so far as their folders names, unless you then  optionally go in and rename the automatically made folder name to add some descriptive words. I don't bother doing so since I think it is more important to characterise the photos themselves (by adding bulk keywording during import). Descriptive text within the folder name is only ever seen in practice when you are looking at these photos in the context of the Catalog. Metadata added to the individual photos follows them into exported copies - including to some other folder, or when exported directly to the web. The source file's folder location is purely a local management matter, and functionally limited anyway IMO compared with the more flexible and productive forms of virtual image management that a Catalog makes possible.

IOW: Folders are a necessary technicality of storing images, that you can safely subcontract out to LrC to implement - but that do not HAVE to then serve as your primary, nor even as a secondary, means of management so far as your image library. 

It really doesn't matter.

But as advice on the bigger issue of using folders, I would advise you to keep your folder structure simple, such as capture date; and use keywords and other metadata to help you find the photos you want, rather than using folders to find your photos. (EXCEPTION: If you already have metadata in your folder names, like "Trip to Boston" as a folder name, keep those and then add a keyword(s) for all photos in this folder, with the eventual goal of having keywords for all of your photos, and all newly taken photos go into folders by capture date with appropriate keywords).
