I get all my 2FA through SMS or a Yubikey. It took a bit of wrangling from corporate IT, but it was "Get my yubikey or SMS working or buy me a company phone and pay for service that I won't use for anything else"

I never really did a lot of banking on my phone before, but it really wasn't that hard to let that go. I'd say the biggest hangup is not having Venmo or something for splitting bills with friends, yard-sales, etc, but I've started carrying some amount of cash again for those instances and it's worked out alright.

Been daily driving a dumbphone since 2023. Yes it takes a bit of work, but it's so SO worth it.
