Tax Questions after marriage

Hi! I got married this year, in April. I am wondering how my husband and I should go about filing our taxes come next April. Neither of us have updated our tax withholdings at work so the taxes coming out of our paychecks have remained the same. We are wondering if we should update these? We need advice on if we should file jointly or separately. We also bought a house in November 2023 so I'm not sure if this affects anything. We have no debt, aside from the mortgage. My husband makes about 2.5x what I do, gross income. I also switched jobs this July. So a lot of big changes have happened and we're looking for advice on what to do! Should we update our Tax Withholdings at work ASAP, wait until the new year, or not at all? We tried meeting with a local financial planner but could never connect, so basically had a string of voicemails going...everything they said was just gibberish to us and not very helpful! Thanks in advance for your time.
