Change Theme Font Sizes

You can change the font sizes, if you prefer them larger or smaller than the theme defaults.

In WordPress, go to Appearance > Customize > Additional CSS

Add the following CSS for changing the most common elements - body font, title font, menu font, and front page 1 welcome message font.
The theme sizes are listed below, so you can make the font-size for each of them larger or smaller, accordingly.

/* Theme Font Sizes */
body {
    font-size: 16px;
}
.entry-title {
    font-size: 60px;
}
.front-page-1 .textwidget h2 {
    font-size: 80px;
}
/* End Theme Font Sizes */

Navigation Menu Item Font Sizes
To make the navigation menu item font sizes larger, add this to Appearance > Customize > Additional CSS.
Change both 12px to a larger number.

/* Menu Font Sizes */
.genesis-nav-menu a {
    font-size: 12px;
}
@media only screen and (min-width: 980px) {
     .nav-primary .genesis-nav-menu > li > a {
           font-size: 12px;
     }
}
/* End Menu Font Sizes */

Adjust the size of the agent name at small screen sizes.
First make the .user-profile p wider - the first CSS section below.
If that doesn't help enough, make the .user-profile .agent a.larger font-size smaller than 32 px.

/* Agent Font Sizes */
@media only screen and (max-width:680px) {
    .front-page-1 .user-profile p {
        width: 100%;
    }
    .user-profile .agent a.larger {
        font-size: 32px;
    }
}
/* End Agent Font Sizes */

Change Fonts That are Capitalized to Normal Case
To change the Front Page 1 welcome message, add the following CSS:

.front-page-1 .textwidget h2 {
    text-transform: capitalize;
}

To change the Front Page 1 agent name, add the following CSS:

.user-profile .agent a.larger {
    text-transform: capitalize;
}
