Max Out ROTH IRA at 40yr old?

Currently 40yr old. I have nothing contributed to my Roth IRA. I noticed the due date for 2022 contribution is April this year for 6k max, and for 2023 it’s 6.5k. My question is should I contribute at my age? I already have a taxable account that I DCA into for VTI, VXUS , BND. I was looking for a ROTH IRA because I wanted to use it for dividend ETF investing. Since you don’t pay tax on dividends and I can cash out to bank. My current portfolio would be several dividend ETF’s that would yield around 5%. After the first year I would only get around $30 a month. It would take a lot of time for this dividend portfolio is be massive. After 10 years with hypothetical sideways market in dividend ETFS I would only have 65k (roughly) which at 5% would only yield $270 a month. Which would not be a lot considering the cost of living will be a lot higher in 10 years as it is today.

Another thing is that to get 5% on dividend investing I have to be in JEPI which is covered call options. Most ETF’s for dividend investing are quite low if I got the traditional route (VIG)

Contributing to a ROTH IRA with this plan does not seem motivating for me. Even though I always wanted a dividend portfolio. It would take me several decades to achieve any kind of substance. (Unless they increase the contribution amount significantly)

Side note: In the taxable account It’s 2.24% yield, but it’s taxed. Also seeing comments about what to do if retired or not. I’m already retired. So not sure if it’s right or not to max out Roth IRA if retired?
