An alternative to Photoshop is Affinity Photo? Non-subscription,
inexpensive and quite powerful and can utilize many Photoshop
plugins.
For Lightroom, at least for RAW processing, I us DxO PhotoLab4
which converts RAWs much, much better than Lightroom and
if you purchase the Elite version, the noise reduction is the
best of any RAW image processor. Also, their lens correction
is superb as the painstakingly test each lens and camera
combinations and not just obtain generic manufacturer data
like Adobe.
In terms of photo management, taking, and browsing, you
can install the Adobe Creative Cloud app and then download
and install Adobe Bridge 2021 for free.
I personally use all three in my photo processing workflow.
