Lightroom is the organiser. Importing the images to Lightroom allows you to catalogue and search.
You can carry out initial processing in Lightroom and only go to Photoshop for things like cloning, combining images together etc. That means for many images, you will not need Photoshop at all.
Yes, Lightroom is the most powerful organizer in Adobe's portfolio.
The great thing about Lightroom is that you can organize on many levels at the same time, and they don't get in each other's way. You can cross-reference using multiple keywords, and at the same time you have immediate access to the physical folder structure on disk. Then there are collections, labels and ratings, and filtering based on file metadata.
You won't use it all. The primary tool is keywords. The trick is to set up a sensible hierarchy. Put some effort into this initially, it will pay off later.
I use Adobe bridge as my organiser... Lightroom is more storage as far as I'm concerned but each to their own
Just to avoid confusion for those less familiar.
Lightroom Classic doesn't store images. It maintains a catalogue of images no matter where they are stored.
So if I search for 'fish' it will bring me all the images with fish in the title or keywords regardless of which disk, folder etc I used to store them.
There is a separate version called Lightroom CC which does store copies of images online. Whether that is suitable depends on how you would use it and the volume of images you take. Lightroom Classic is better for my use. But have a look at both and you can make a sensible decision on which is best for you.
ok to be clear, I open | sort | keyword and delete images in Adobe bridge first before sending them to storage in Lightroom... I have both CC (on my Ryzen) and classic (on my laptop) but I don't keep every image I take on my cameras and imo Lightroom is not very good at sorting images until Bridge has done its thing
I do agree that different people may have different needs | workflows and there is nothing bad about Lightroom
