Well I run GrapheneOS on a Pixel 5, and I use Shelter to isolate my work apps from my personal apps. I have sandboxes google play within shelter, the apps I have in my work profile are:
I dont use my phone very much for myactual job, but its good for maintaining connectivity and checking/responding to emails and calling into meetings as needed.
Mostly mental, and ensuring separation between my real life work identity and my online/whatever identity. I’m sure that’s mostly in my head but peace of mind is peace of mind.
