Good recommendation. Good to remember that each app has its own sandbox so for most scenarios you are all set anyways (except running google play in general you may be against).

An excellent middle ground, if preferred, would be your main profile with everything that works anonymously and without google, etc, then a second profile that is not so anonymous (ie banking, google maps, etc).

You also likely need your password manager app in both profiles.

p.s. if you also use fingerprint (or any biometric) unlock, remember you can hold the power button to go into lockdown if you ever have a security threat (ie think you might be arrested or robbed or whatever like that). This disables biometrics and requires your pin. (i believe you should do this even if you use only a pin since it takes your phone into a BFU state, which you can google more about if interested).

Is fingerprint unlock not secure/private on android?

Very interesting. I was cpnsidering using separate profiles, but I read somewhere that google services is sandboxed anyway, so having it all in 1 profile is fine.

What I will need a separate profile for though, is for banking apps. I have one which is adament that I use a keyboard app from the play store and will refuse to function if I have one from F-droid installed.
