Where to keep Roth IRA if I want to do options

I’ve got about $22k in a Roth IRA at Vanguard and want to sell cash‑secured puts in my retirement account. • I already use Fidelity and Robinhood for options in taxable accounts. • Vanguard’s interface feels clunky and they charge $1/contract to open and close For CSPs in IRAs, would you move to Fidelity or Robinhood, and why? Which do you prefer for usability and handling assignments in an IRA? Also, Vanguard may charge a $100 fee for a full account closure/transfer out. With that in mind, is it better for me to just transfer/close the Roth IRA and leave the empty IRA open at Vanguard, or is it still worth fully closing everything? Thanks in advance.
