perfect-vision VS macros

in foundry v10 you can do that with the module perfect vision which can set up areas where global illumination is disabled, alas some change in foundry v11 make updating the module too complicated for the author so he abandoned the project

You can use the module Perfect Vision to draw areas of darkness, limited vision etc.

Alright, this isn't a direct answer to your question, but more of me trying to answer what I think your problem is. I believe the solution is using https://github.com/dev7355608/perfect-vision

Perfect Vision: Improved vision support

Yeah, learning how to do other stuff in Javascript is a good way to start. But then maybe look at things like the example scripts in the community macros: https://github.com/foundry-vtt-community/macros

Have a look at the community free macro module. https://github.com/foundry-vtt-community/macros

If you code at all, then Foundry jumps even higher up the recommendation list since it's designed intentionally to allow people to build stuff and add functionality. As someone who used to mess with R20 macros and their proprietary API, this is probably one of my favorite benefits to Foundry. They have some typical documentation though if you prefer examples the community macros repo is great for that.

Read some of the shorter/simpler macros from https://github.com/foundry-vtt-community/macros to get a sense of how they work.

This macro in the FoundryVTT Community Macros GitHub repository "selects all actors of the same name on the scene." I haven't tested it, but these macros have never given me issues in the past, and I recommend checking out that repo if there's ever something you're looking for.

Quick size control (#2) is generally handled by macros. There's a macro for quickly swapping tokens between 1x1 and 2x2 in the community macros. If you want some that will just bump a token up or down 1 grid size, I can get you mine personal ones in a bit when I'm at my main computer/
