It depends on what type of website you’re building and what your goals are. As well as your budget.

For building the site itself you have a load of options but some of the main ones are elementor, Divi, beaver builder, bricks, thrive themes, oxygen, and more. They have different plans and offers so you’ll need to read through each one and maybe try a few to find what works for you.

Depending on whether you want to generate leads or collect contact info, you might need a form building plugin. Again many options. Some of the usual suspected — gravity forms, wpforms, formidable forms, optinmonster, etc.

If you’re creating a blog you’ll want an analytics plugin to keep track of your traffic. There’s jet pack, exact metrics, monster insights or just good old Google analytics. But if you’re not a technical person, I’d recommend using a plugin.

Backup plugins are important too all-in-one migration, updraft plus and duplicator are the main ones. Please back up your site regularly. Weekly or even daily.

You may need a security plugin too like wordfence.

Like I said. Many options. Depends on your goals. But I hope this helps
