I've had a Galaxy Note 4 for many years and am still happy with it,

reinstall the Apps I want, but this is also an opportunity to root it.
Rooting a phone is new to me so I have no idea how easy or risky it
is, which ROM to use, and whether the benefits outweigh the hassle.
All opinions and experiences gratefully received.

XDA is a good place to start. https://forum.xda-developers.com/note-4

I have a bank app. The installation instructions said app would not work
if the phone was rooted.

In which case, go back to them and get one that does work.

I don't think you need to root a phone to replace the OS, just unlock
the bootloader.
