Plugins that Help your workflow
Power save. Allows you to save easily, and adds incremental numbers so you know the latest one. Must have Plugins
https://github.com/elfnor/blender_auto_save_on_render - so a buddy lost work because blender doesn’t automatically save the project before it renders - it should thats a great way to make sure the render matches the images. So this is a good plugin.

Plugins that need further investigation
https://www.blendermarket.com/products/fluent Fluent seems like a really good plugin to model. Maybe I'll review this plugin.
Home · gregzaal/Gaffer Wiki · GitHub I only tested this one out a little bit, it wasn't immediatly obvious how helpful it was
for lights. One feature that is good is click the light and an object and click the active button and it points the light at the object. Helpful. Its located in the side panel in view.\
Good Plugins that 2.91 blender has but are turned off by default
Simply turn these on in preferences under add ons.
Extra Lights, Has a few extra lights that you can add
Extra Objects Has a few extra objects that you can add.
Camera Rigs THis plug in sounds good in theory, but I have to read the docs.
Copy attributes menu, Dynamic Brush Menu, Dynamic Context Menu, MOdifier Tools,
Dynamic SKy Ecellent automatic sky settings for different times of the day.
Material Library:This plugin is like presets for nodes, Only thing is there are no thumb nails and slow. Must Have Plugin
Also it acts weird when applying the material to more than one object. You have to Make a new surface
And in the Material Utilities apply material to active to be able to use the same material but make tweaks to noise or color.
Material Utilities.This has good shortcuts on the right mouse button click menu. Must Have Plugin
Node Wrangler I think this is on by default. You should learn the shortcuts like shift control Click on the bsdf shader. If you select a folder with all the images labeled normal, color, bump etc. It will automatically apply them as nodes with geometry and mapping nodes. LIly shader is one step above this though. Must Have Plugin
Object Align Tools. (haven't used it yet so I’m not sure what this does.)
3d view stored views. (I like the idea of this plugin, if your in view and like the view, click on new camera and automatically add a camera. You can add several.
Archimesh make a house quick
Archipack Make a house quick Add in windows, doors etc
Ant landscape is for making landscapes. It’s ok I guess Not sure what else you could use.
Turnaroundcamera is good for making a turntable animation easily. (haven't tried)
BoolTool is good for boolean operations in a convenient place on the side view Must Have Plugin
