Ok so I have a Google account for an organization. But when I have that account logged in on my phone some of the security restrictions impact all accounts on my phone. I have a pixel 7a with Android 16 if it matters.

I would love to have access to this gmail account, with notifications, on my phone without forwarding the emails to one of my personal accounts. Any way to do that within the Gmail app itself, or if I need a different app, any recommendations?

In my perfect world I'd have OneDrive access too, but I can use a browser window there if needed.

I'm getting a new phone (OnePlus 13, not that it really matters) and I'm considering the benefits of flashing over something like LineageOs straight away rather than using the stock OS.

Normally, I expect? You'd run stock until security updates stop or something changes where you want a longer running OS, but I'm considering it because I cannot be bothered with all the bloatware they put on modern phones these days.
Plus it should save a heap of battery.

What are people's thoughts on this? Is it something you always do anyway or do you usually run stock for a while?
