I recently upgraded my iPhone and kept my old one, which is connected to my Apple account, and therefore the iPhone Mirroring app on my MacBook running MacOS Tahoe. Whenever I try to mirror my new phone, regardless of whether I am near my old phone, it always tries to connect to my old phone. I have tried restarting both my MacBook and my new iPhone, powering off my old iPhone, and nothing is working. What should I try?

See this Apple Support document about iPhone Mirroring on the Mac. iPhone Mirroring: Use your iPhone from your Mac - Apple Support
There is a section on how to change devices included there.
Found a solution through the article ChrisJ4203 provided: Mac System Settings > Desktop & Dock > Widgets > [Select desired iPhone]
Make sure your connected on the same wifi and the same account, and turn Bluetooth on. If these does not work, it’s a technical issue, so use this at your risk: reset your Mac and put everything back, but if that still does not work, you must contact Apple support for that!
