The "resource" part of my domain name should hint to the fact that I am obsessed with finding all the possible resources I can to do better in business.
When it comes to building websites with WordPress, there is no shortage of resources. These come in the form of plugins. I've gone through (and I shit you not) hundreds of different ones over the years.
Some work great, others destroyed my site and cost me a lot of time and money.
Here are the plugins that I am actually still using on this domain (a domain that earns over $70,000/month no less).
Also, I use most of these plugins on all the other sites I create for myself and my few by lovely clients.
Content Creation Plugins
Quick Note: A Theme isn't a plugin, but the Theme I use is included with the Thrive Themes Product Manager plugin.

Thrive Architect (Part Of Theme Themes Suite)
This is my bread and butter. It's like the paint brush for a painter. Thrive Architect frees me from the default vanilla editor that comes with WordPress.

Smart Slider 3 Pro
This is far from as necessary as the Thrive Architect, but if you like creating highly visual content with slideshows, you'll enjoy this.

Thrive Apprentice
Another plugin that comes included with the Thrive Themes suite of software. Thrive Apprentice lets me build courses inside of WordPress. These are gorgeous looking and forced my hand in leaving Thinkific as my exclusive course hosting software.
Lead Generation Plugins

Thrive Leads (Part Of Theme Themes Suite)
If you've seen any pop-ups or opt-in forms on this site, those were displayed via Thrive Leads. The template forms are rock solid but you also have limitless freedom in customizing them to your liking.

One Press Social Locker
Boost social shares by hiding content behind "share walls." When users share content on various social media channels, you reward them. I don't use this a ton but it works when I do.
Spam Defense Plugins

Akismet AntiSpam
No matter how big or small your blog is, you'l be flooded with spammers the second you turn on comments. Akismet crushes all of them.
Speed Boosting Plugins

WP Rocket
A powerful caching tool that keeps my website lean and fast.
SEO Plugins

Yoast SEO (Premium)
There are literally hundreds of SEO related WordPress plugins. Yoast is the gold standard for them. That is assuming that you invest in the premium version (the free version is fine but not enough).

WP Sheet Editor (Trio Of Plugins)
There are literally hundreds of SEO related WordPress plugins. Yoast is the gold standard for them. That is assuming that you invest in the premium version (the free version is fine but not enough).

LinkWhisper
Internal linking isn't sexy, but LinkWhisper makes it easy. You can quickly fix years of poor internal linking in less than an hour. Seriously. It's that powerful.

Auto Image Attributes Pro (2x Plugins)
Much like how LinkWhisper can fix years of bad internal linking, Auto Image Attributes Pro can fix years of poor image tagging.

Export All URLs
This plugin is super simple but I've found so many cool uses for it. All it does is export your content into CSV files. I've used this to create content update worksheets in Excel.
Sales Boosting Plugins

Thrive Optimize
Thrive Optimize allows me to create A/B tests of any sales or lead generation page. Powerful (if you remember to use it).
