node.js - Global installation vs under nvm

Question

I have several states of global packages between my machine/server/staging. All of them use nvm, and my impression was that all the packages should be installed under it. Locally, for example, I have:

which yarn
/Users/***/.nvm/versions/node/v14.15.4/bin/yarn

It looks fine until I switch the node version selected by nvm:

nvm use v12.19.1
which yarn
/Users/***/.nvm/versions/node/v14.15.4/bin/yarn

Q1: Is it okay that yarn is installed for v14.15.4, but is used under v12.19.1?

On my staging/production machines I have yarn installed globally:

which yarn
~/.yarn/bin/yarn

Q2: Is it okay that yarn installed globally? Is it better than to install it under nvm?

For production, I have pm2 installed globally by yarn, while nvm is used:

which pm2
~/.config/yarn/global/node_modules/.bin/pm2

Q3: Is it okay to have it globally installed?

For staging, pm2 is installed under nvm:

which pm2
~/.nvm/versions/node/v14.15.4/bin/pm2

Q4: Is it okay to have it installed under nvm?

Q5: Which node version will be used on personal/staging/production machines for yarn/pm2 after I switch it using nvm?

Q6: Are there differences for these questions between yarn/npm (if I was using npm instead of yarn)?
