I'm in a similar camp where I'm stucking to windows for that one software: lightroom classic (or CC as they call it). I'm happy to pay for a legitimate replacement that lets me go Linux native on a laptop. I'm fine even paying for the Adobe Cancellation tax from the money I save not buying Windows.
On that note, is this supported on Linux?
Have you tried Darktable or Rawtherapee? Both are excellent alternatives to LR.
Yes DaVinci Resolve is supported on Linux. Unfortunately the free version of DaVinci Resolve does not include H.264/H.265/AAC support on Linux due to codec licensing issues though you can transcode it elsewhere first.
