Hi,
1/ If you want to use child theme, please move the customization data from parent theme to child theme by do following steps:
a) Install & activate plugin Customizer Export/Import
b) Keep activate parent theme > go to Customize > Export/Import > and export the customization data > you will get a .dat file.
c) Activate child theme > go to Customize > Export/Import > and import the .dat file you got on step b.
2/ Install plugins doesn't based on the theme you're using. Example if you install Yoast SEO plugin, when you change to any theme - the plugin still keep installed on your site.
3/ If you want to use child theme, let's install it as I said on point 1 - after that, import a demo.
4/ Let's install child theme, after that, add your custom font via Dashboard > Soledad > Custom Fonts > upload your custom fonts here and set a name for that font.
When you done, go to Customize > General Options > on "Font for Heading Titles" and "Font for Body Text" > select the font you've uploaded.
Best Regards,
