I need to be able to customize it, having it pull things like weather, sports times/standings, data from YNAB, to do list, etc. Have it update every so often.
Does this exist? If it doesn't, where do I start as someone that doesn't code?
I'm a big fan of this idea. I've also at times longed for something that could track my finances, fitness / sleep, and productivity data.
This looks interesting: https://www.thedash.com/
If you can't find an existing solution, I would start by putting together a description of exactly what you're looking to build.
From there you can either try and find a technical person willing to help out, or hire someone via a site like upwork.com
I'm decided to just start on it. I'll use it to give myself an intro to HTML and Python. So far just a simple page with a clock. But it's something!

It probably isn't useful to you as a non-coder though. :)
