Hello @Comboss,

We would need to access your site URL to precisely suggest you on decreasing logo size and the site titles specific to your site.
Until then, you can simply paste in the following custom css in your Admin Panel > Appearance > Customize > Theme Options > Advanced Options.
Here you will see a box to write Custom CSS. Now copy and paste below CSS to get smaller logo and relative site titles alignment.

.site-logo-link > img, .custom-logo-link img {
    max-height: 80px;
}
.site-title {
    font-size: 18px;
}
.site-description {
  
    font-size: 12px;
}
#site-identity {
padding-top: 12px;
}

Hope this will help you.
Let us know how it goes.

Best regards!!!!
