What advice do you have for someone considering transitioning from E-4 to an Officer?

I recently enlisted as an E-4 (active duty) since I have a college degree, for 68W. I ship out next month (Jan 4) but I was having second thoughts about commissioning as an officer instead. My recruiter really pushed for joining as enlisted rather than an officer, saying that I could always switch later by submitting a packet. But I feel like that sounds easier said than done based on things I've read about it. He did mention that I did have the scores for officer though. I also chose 68W since 68G wasn't available at all. (I am pursuing dentistry) I was also offered intelligence but I thought it would make more sense to do a 68 MOS.

A little info about me: I had to sign the contract as an E-1 because I couldn't get my official transcript copy due to money owed. Now that it has been taken care of, I will be going back to MEPS to update my rank. Also, my original plan was to apply for the HPSP once I apply (and get accepted) to dental school next year and either become an army dentist or civilian dentist, but decided to join the army earlier since the pandemic has made my gap year really difficult. I still plan to apply for the HPSP next year once I finish AIT.

Any honest advice?
