You started your FSA coverage on December 5, 2022, right? That is, you didn't start any FSA coverage until you got married, right? Since the coverage you have on the first day of the month is the coverage you have for the whole month (in your case, HDHP, not the FSA), you were not covered for any month by the FSA in 2022. Therefore, you had no conflicting coverage to your HDHP in 2022, and so there is no effect on your 2022 return.
You seem to have started out 2023 on the right foot, but I suspect that you will want to drop the FSA and restart the HDHP coverage as soon as you can (which may not be soon) because the HSA program is almost certainly a better deal for you than the FSA.
P.S., You have until April 15, 2023 to contribute to your HSA for 2022 (remember you must specify that the contribution is for 2022) if you want to "fill up" the contributions to the limit for 2022 (which will be the normal HSA annual contribution limit).
