To me the major distinctions are near full functionality even if I'm offline and the app hasn't been used in a long time and offline-first design with all major assets being available for download ahead of time and/or transferable between devices without re-downloading

Sure, but when it is for things like "reimbursements, documentation and reporting, gathering and presenting business data. That sort of thing.", I'm not really sure offline is that big a requirement, or that there are that many major assets. Even so, your mobile browser should be able to cache CSS and hero images.
