Offline-local plus additional cloud integration is definitely viable in most cases. You do have to either have teams developing for multiple platforms or limit yourself to one platform.
For offline-first the money isn't on the software, it is on the hardware and maintenance. So it isn't something that VC or other wild speculators would enjoy.
You'll make a living, maybe build a team and that is likely as far as it can go.

Of course: YMMV
It depends on who your customer base is and how much you hate them.
