Hello there,

I hope you are doing well today.

Storefront is not a them that was created b us so we would not be able to provide support for it however this CSS code should help you out:

/*Menu font bold*/
.main-navigation ul li a, .site-title a, li a, .site-branding h1 a, .site-footer .storefront-handheld-footer-bar a:not(.button),, {
    font-weight: bold;

Best Regards,
