Lightroom Classic for me. I organize by year and then high level subject and add keywords (current year is always by year/month/day folders and then reorganized at the beginning of the following year). I have a Master catalog that holds everything (most of it backed up to external drives and backed up) and a working catalog that will hold the most recent 1-2 months work where I can process them, delete the crap, and do the necessary. Then once a month I'll move the photos to the external drive, go to the Master catalog, and then use Import From Catalog to pull in what I just moved. Once there I'll remove (don't delete as it will remove the image from the drive) them from the working catalog. Seems like more work than necessary for most folks, but it keeps the catalog I'm active in more nimble with the other containing more of what my "catalog" of images is.
I also shoot Infrared and Drone work and I keep that work in a separate catalog.
