I use Lightroom intentionally to keep photos out of the Apple library and camera roll (which I treat as transient, temporary work areas).
Photos are too important for me to trust to only Apple (Lighroom/Adobe tools are cross-platform both on computers (Mac and Windows) and mobile (iOS and Android).
I also enjoy that if nuke my iOS or Mac devices, I don’t “white knuckle” worry about my photos or suffer long extended re-sync from the iCloud times.
For editing, I never crop any photos. A bit controversial, but as a former part time photographer I bought into the “crop with your eye/mind/feet” when you take the picture, not later. Helped me take better pictures by not kicking the composition can “down the road” to post-processing time.
I have also switched to shooting almost everything in raw instead of jpeg. Also a bit controversial, but actually makes using a DSLR or mirrorless camera a lot easier as many of the settings people sweat over don’t apply to raw mode and big errors in exposure or color balance can be fixed later where jpegs are “baked in” when you take the photo and have much more limited corrective range.
On iOS, I use Lightroom as my camera app most of the time - it shoots raw and I use it “point and shoot” mode or I will use specialized photo apps that have raw mode and manual controls, but I don’t use them too often.
Why raw? Well it is the digital equivalent of saving the negatives rather than just the inkjet printouts. With so much advancement in what is called “algorithmic photography” I want to be able to apply future improvements to past photos.
In the next 3 to 5 years the “auto” button in photo editors will be orders of magnitude smarter than today. With raw files my existing photos will get the same benefit as new photos taken in the future. (The assumption is that sensors and especially lenses will not advance as quickly so the raw image captures of today will still be relevant)
