Yes and yes.
You were married as of Dec 31, 2022, so you have the option of filing MFJ or MFS. If you want to amend 2022 and change from MFS to MFJ, you can do so.
You can claim your child in both years as a dependent. She lived with "you" in 2022, even though the "you" is your spouse in this case, but since filing MFJ, it doesn't matter that she lived only with your spouse and not you.
