I would say Dividend Investing is better when you're near or post FIRE. Then, a solid company cash cow paying solid ~5% dividends (and growing them) gives you some reliable regular income and exposure to the general stock market (tho long term probably under performs equity index, medium term who knows?).
And even then, you want them in a tax protected account.
For you, at your age, I'd go 90% total market index buddy. If you can, meanwhile buy and live in a run down house with solid bones in a growing area, fix it up, sell after 2 years (tax free cap gains), and repeat.
