Should I minimize the use of custom fonts?

As an e-commerce business owner, I'm struggling with website design and performance optimization. I've heard conflicting advice about custom fonts - some say they enhance brand identity, while others warn about potential performance and loading speed issues. I want to understand the strategic considerations behind font selection, particularly how it impacts user experience, site speed, and conversion rates. What are the pros and cons of using custom fonts, and how can I make an informed decision that balances aesthetic appeal with technical performance?
