I have built this site (gauravtiwari.org) and many others on Marketers Delight (MD) WordPress theme. MD has a powerful design system with inbuilt hooks, powerful filters, marketing optins and inbuilt Gutenberg support. It is both fast and beautiful at the same time. It’s priced at $58 for one site, $97 for 5 sites (yearly) and $297/one-time for 25 site licenses. But if you buy a license you get usage on unlimited sites with automatic theme updates on one to five sites depending on the license.
Renewals are offered at a 40% discount, so if you are serious about your online marketing game — Marketers Delight is the theme for you.
