Fidelity Go vs Managed FidFolios

Hi everyone! I am looking for advice for what secondary account I should open to put in extra money into the market. I am in my early 20s and have already maxed out my Roth IRA for the year. Should I have someone manage my money though the services Fidelity provides or just put my extra money into funds on my own? For example, VOO or any of the Fidelity managed funds.

Any advice is appreciated, thank you!
