Plugins for a new Website

As a starter, it's tough to make a website as desired.
We need to research the plugins and find the suitable one.
So, to reduce the time can someone tell me a few of the plugins that can be very helpful for a new website in WordPress?

Depends on what kind of website, but WP Rocket and WordFence Premium are amongst my defaults for a fresh install.

Well since you posted in blogging section so with regards to blogging or a niche site any fast loading theme like schema or generatepress.
I think some of these plugins are a good choice:
Table of contents
WP fastest Cache
WP Optimize
Rankmath SEO (Optional)
Any Backup plugin (Optional)

The golden rule is to use only the plugins you really need, and as few as possible. In your case, what kind of site it is? You will use only for blogging, or you want to sell through it?

A possible list:

SEO - The SEO Framework

Analytics - SiteKit by Google / Perfmatters have this option, too (so -1 plugin, if you use Perfmatters).

Caching&Speed - The best thing to implement would be the "Nginx/FastCGI microcaching" method, if you can control your server - Usually on VPS&VDS. If not, here are other cache plugins: Surge (free)/LiteSpeed Cache (free)/WP Super Cache/W3 Total Cache. Or the premium ones. Perfmatters is a useful tool, if you want to get rid of unused scripts.

Security - Wordfence/Sucuri + server&.httaccess tweaks +2FA

Backup - Updraft is the best.

Shop - WooCommerce is the most known (+ many more addons, depending on the kind of your site).

For all of my websites, I use these ALWAYS. The new or old website, I use them on every site:

1. Rank Math SEO
2. LightSpeed Cache
3. Smush
4. Askimet Anti Spam
5. Insert Headers & Footers
