I moved across the country a few years ago, and just a few months ago got a new phone on a new carrier. For a brief moment, I considered getting a new number. No more spam texts and calls (or at least different ones)? Having an area code matching where I lived? Seemed like positives, and it'd take me about 10 minutes to email or text my new number to the relevant parties.

I hadn't considered MFA because I use Authenticator and have most of my TOTP seeds in 1Password anyway, but man I'm thinking I dodged a bullet because there are a handful of things that use SMS only.
