I regretted it too after I went with an SE 2022. I thought the battery life would be better, and I thought I didn't want to swap Touch ID for Face ID.
18 months ago I bought a used iPhone 13 Mini, and much prefer it. I used to feel unhappy every time I held the SE 2022. I never liked the wider, rounded-edged shape of the iPhone 7/8. I'm finally going to get a battery swap for the 13 Mini from Apple this afternoon.
I'm hoping that stops me vaguely wondering about battery swapping for my SE 2016 (1st gen) and going back to using that. I don't think I'd want to go back to a camera that old, and too many apps are not supported. That was the last iPhone I really loved. Fastest smartphone on the planet in benchmarks when it was released, and in the rare event that it slipped out of your (someone else's) hand, it felt unbreakable compared to newer iPhones.
