If you care about your actually owning your device, install something else than stock OS. I would recommend GrapheneOS, since the security of some/most other alternatives is pretty bad.
So, you have to wonder whether you want such a phone anyway if you care about security and privacy. If you don't care about security anyway, you could as well run /e/OS, etc.
Above-mentioned Samsung phones could perhaps make the cut, but don't support unlocking anymore (and when they still did, would blow a Knox eFuse).
I get all or nothing when your threat model is state actors. However, for most people, the benefit is just freedom from corporate agendas.
Not everyone needs kernel hardening, or always E2EE (as with signal). Personally I just like the features it provides (e.g. scoped storage, disabling any app including Google play services, profiles etc etc
Its also an easier sell to people who are apathetic to security when the product is just better and more secure, the same way apple does (for whatever their reasons may be).
All that said, I get they're limited in funds and manpower, plus the things mentioned at the end there, so I can only be so peeved they chose a target and stuck with it. They typically cite security as the reason, not those other ones, however.

grapheneOS only works with google phones.
Better yet, you can buy a used pixel phone.
Not a bad deal and pretty crazy how fast smartphones depreciate now.
Many banking apps do work on GrapheneOS, the list had already been linked to by others
2FA. I was a smartphone hold-out for longer than anyone I know, but banks mandating 2FA with no options for doing it in a standards-compliant way or any way that doesn't involve the app stores was what finally broke my resistance.

If the bank is very hard-nosed about it, you could consider keeping an old iPhone or Pixel (because long security updates) for banking if it is practical to do for you. 95% without big tech is also a big win. Of course, if you need to have it with you at all times, that might not be a worthwhile option.

Also, what kind of banking are people doing that requires an app? I genuinely don't know what it could be.
Close to every bank in the EU requires their user to have an app, for MFA (both for logging in and for validating transactions - transfers, payments). They use the smartphone's TPM. I have yet to see one that allows you to use your own MFA app.
The few I've seen that don't require it will validate the same through text messages (not everyone has a smartphone); though if you associate their app even once, you're screwed - the app it is from now on.
Possibly this was hyperbole but in any case it's not correct at all.
Anecdotally, of my two EU (massive legacy French) banks, neither requires a mobile app. SMS all the way.
Even Wise, a cutting-edge neobank, does not require you to use its app. And its website accepts standard TOTP authenticator for 2FA.
Revolut is app-only, which is why I never use it.
Especially since in many countries it requires a national e-ID that is an app on your phone.
Horizontally splitting Google into multiple companies.
Not division via department splits, but equal partitioning across the company into multiple horizontal businesses that compete on the same offerings.
The EU and next DOJ/FTC need to force this.
The EU is not going to force this, because it has enough fights to pick with the US, and this is not the hill that they are willing to die on. It would be far more likely for them to financially support an AOSP-based OS.
