I know you didn’t ask for alternatives, but since you have a Pixel I thought I’d at least mention it.
Have you tried GrapheneOS?
My battery life is amazing with it and I’ve never had any overheating issues.
Edit: my local credit union app works fine. You can even relock the bootloader after you install graphene.
I currently use this fork of OpenBoard since its actually getting updates and a ton of fixes. supports glide/swipe typing. Then Bitwarden like someone else mentioned. Pops up in a drop down when you click a username field.
I meant the app similar to edge panels.
