Designer's Pick | https://open-foundry.com/fonts
Open Foundry is my favorite stop for free commercial usage fonts, these typefaces are extremely well-made, eye-catching, and have various styles/weights. The website also allows you to test their fonts on various backgrounds and colors to see how they work. All fonts are downloadable and can be used freely in your designs, I commonly use fonts featured on their website in my works and I hope you do the same!
