I'll chime in with the same preference as everyone above. Lightroom Classic CC as part of the photographer package (with Photoshop) is the way to go. Best practice is to store at least two copies of your raw files on external hard drives. Cloud storage is far too slow and not an option on most international dive trips.
There are also a few things to consider before jumping in, primarily file naming structure and organization of your library (folder structure). Many do this by year and location, but it's all personal preference. Erin Quigley is another great resource for Lightroom.
