Flexible Position to Move Into

I work for a fast growing start up company (I think I've said this a lot in my WR posts so I apologize) as a BDR and I am looking to move into a new role by the end of the year.

The three career paths I currently see in my company are CSM, Sales Ops and AE (BDR manager is off the table as that role is filled).

I think CSM is my next logical move and yes I've read the following posts.

My company provides a large amount of flexibility which is great because I have a very time consuming side project/ hustle that I am committed to for the next 5 months.

My question is what position, CSM, Sales Ops and AE provides the most flexibility within the day to day?

I'm not looking to skip out on work but it would help if my mornings were more free and I could work later into the night.
