CLOZ
Eldridge BBB-B CLO ETF
stock NYSE ETF

Depends on:
1) when you need the money
2) contingencies plans if you don't have all the money (buy a lesser car, sell something else, etc.)
Generally speaking equities (such at VT) can go up or down over a 0-5 year window of time. They have a bias to go up.
If you want to know that you'll have exactly a certain minimum of money on a certain date, invest in SGOV.
If you need a reasonable probability that it will go up over a years time, and it won't be devastating if it falls short, there are low(er) volatility options like JAAA, CLOZ, DIVO, JEPI that you may want to look into. Again, can still go down, but a tighter tolerance of expected outcomes

For dividend you should avoid individual company stock. They occationally unexpected file for bankruptcy and and go out of business. If that happened you could lose everything. Also if the company cuts the divide or stops paying you have no way to compnate. ETF are bettered byecasethey hold a lot of companes so if one gores bankrupt ofr stops paying dividned you might not notice and the managers of the fund will likely replace that bad company quickly. if it is an actively managed fund... CEF are similar to ETF but they generally off yields that are little higher. Also if using a taxable acount focus on funds that generate qualified or ROC dividend which are taxed at lower rates.
I have QQQI a covere call fund. iT uses a trading stratagy that is very tax efficient due to ROC and has a 13% yield I alas have SPYI 11%,, KGLOD 11%. But you don't want to rely on only covered call funds for income. In a recession the dividned income will likely drop but how much is debatable. I prefer to not automatically reinvest the dividned. I prefer to reinvest the dividned income into other funds that don't use covered calls.
I also have conventional CEFs UTF 7% yield and UTG, 6.4%, and EMO 8% and I ha eoneETF PFF All are very reliable with stable dividneds.
All the above funds I have mentions pay montly dividneds and are tax efficient with either qualified or ROC dividends. In my Roth were taxes are not a concern I have ARDC 9% PBDC 9%, CLOZ 8% , PFFR 8%, JAAA 5.5% which are not tax efficient funds.
I currently have 5K a month from tdividend income in my taxable account Enpoug to cover all of my living expense. I would also recomend you look at Armchair income on youtube for more dividend fund ideas. He does very good reviews of fund that you might be interested.

If you want backup income put GPIQ in taxable Brokerage account and VGT SCHD in a roth or other retirement account. The reason for this is taxes and withdrawals. IF you want access to the dividend income you cannot access it in retirment accounts. For taxable brokerage accounts to is no restriction to accessing dividend income.
Now people will tell you not to have dividends in a taxable account They assume all dividends are taxed at the income tax rate. But GPIQ generates about 80% ROC dividends This basically means the 80% of the dividends will not be taxed of about 10 year. The remaining 20% is taxed at the long term capital gains rate. In the 11 year and after that the income is taxed at the long term captial gains tax rate. Worst case only 20% of the dividend income is taxed. This is effectively a 80% tax discount over the work income / interest tax rate. I would recomend also turning off dividend reinvestment. This will cause the dividend to appear in money market acount were you can either spend the money or reinvest it for more dividned income. YOU keep about 6 months of living expenses in the money market account as your emergency cash fund. And eventually you can use the cash to pay the yearly deposit into a Roth.
Now for your taxable you can use a lot of dividend funds the generate qualified dividends. I am currently using QQQI (similar to GPIQ), and SPYI 11% yield, EMO 8%, UTF 7%, UTG 6.4% and NAC 7% (A CA municipal bond fund which is tax free for me) And PFF 6%. All these pay monthly and are taxed at low rates.
The Roth is a grate account for retirement or long term investing. You could have VGT, SCHD, SCHG GPIX. and any other north or divided funds you want. I have enough growth in my taxable and 401K to my roth is mostly Dividend funds that are not tax effficient like ARDC 9%, PBDC 9%, CLOZ 8%, PFFR 8%, JAAA 5.5%

No what you were doing was buying the S&P500 SPYI and VOO. And then adding JEPQ and NasdaQ 100. And VTI which is most of the E+US market. But all of these indeed are market cap weighted so you are overwieghted in the MAG 7 stocks. These stcks are the the 7nbiggest companes in the Use market. So you largely just kept buy8ng more a dn more of the entire US market.
Index funds are great for for growth investing. For growth you want to hold as many stocks as possible so that they your portfolio mimics the growth of the overall markets.
For dividned investing proper diversification is having each fund invested in different companes or assets that pay dividneds. That can means a fund invested in BDCCs, 1 for MLPs, another , for banks, another for manufactures, commodities, and US gov bonds, Corperate bonds, CLO fund, and covered call funds.
I would drop VOO and stick with VTI. I would keep SPYI. JEPQ is OK abut not tax effieictn so if tax efficiency maters replace it GPIQ or QQQI.
But all the indexes you own don't have any MLPs Mster limited partnerships. or BDC s (Business Development Commpanies. SO I would add PBDC 9% yield for BDCS and EMO 8% yeild for MLPs. CLOZ for BBB rated CLOs, JAAA for AAA rated CLO funds. SPYI and QQQI are good for tech, major bands, manufactures, and. For comofities like gold IAUI work well 11% yield, and ther are others for silver and copper.
