JEPI vs JEPQ in regular account or Roth IRA

21, just started investing earlier this year with a time horizon of 30ish years. I’m not too savvy on the market but want to learn more. What would be the main difference in investing in JEPI and JEPQ or would you recommend to someone beginning now to invest in both equally? And one thing about the tax on dividends, would it make sense to invest using my Roth IRA or standard account. My guess is using Roth IRA would be fine but I’d be limiting profits later on because of the $7000 limit per annum. I could be wrong though, open to any suggestions. Thank you.
