As I understand it, the options will be

• Enable developer mode, wait 24 hours, enable installing unverified apps directly on the phone. My banking app refuses to launch in developer mode and I expect other banking apps to behave similarly
• Sideload over usb. This seems like the lowest friction approach but it's quite inconvenient and unclear if app updates will also need to be installed over usb

So not as bad as apple, but still very bad imo
