Yes, I have an older phone running LineageOS for that matter.
But those are typically community efforts, so software support is not certain. It sucks when so many things just expect you to have a working cell phone.
What company will jump in the competition meat grinder between Google and Apple. Maybe if it’s state-sponsored. I don’t know how much HarmonyOS/Huawei are state-sponsored so I can’t claim there are.
One from Europe is the most likely contender. The disdain for USA corporations is growing abroad. Could even see Canada and Mexico moving to such entities when a solution is viable.
I have been investing in possible startup organizations. We need it!
How do you deal with things such as mobile banking? So many services just presume you use either an Android or IOS.
At some point I thought I really needed Android Auto, but I can probably just get a MStick only for that. There are other things that keep me jailed to Android though.

One way is to have a spare Android phone sitting at home with no sim-card. Also many (not all) banking apps work with Waydroid. The best way is to switch your bank to one not forcing the duopoly on you.
Punkt has a phonen using a fork of grapheneos out of switzerland with some cloud services like VPN attached to make it a completely degoogled 'secure phone', called ApostrophyOS
Mobian, PureOS, postmarketOS exist.
