There are a number of things that can and need to be done to improve the render.
1. The phenomenon you are encountering is called Z-Fighting. As @kandennti has already described, the volumes must overlap. You also need to give the glass a higher dielectric priority. For that you need to change into the render environment and find the glass bodies in the browser. Right-click on a glass body and select "dielectric priority" and change it from the default to 1 or higher.
2. Without fillets on all of the sharp edges there are important reflective highlights missing in the render and it will look very artificial. So fillet all sharp edges.
3. For the ultimate bit of realism you should model the meniscus as that also provides important reflective highlights.
To showcase what it means when these suggestions are applied to the model I created this render.
I also changed the material of the liquid to a glass material, but then changed the glass material. I changed the IOR to 1.33, the absorption color to red and the absorption distance to 3 cm.
Here's another render one just for fun 😉
The HDRI used for illumination is too low in resolution to serve as a background image.
in case anybody was curious to see how my corrections turned out.
Adding a meniscus would be a great idea, but i think the added time figuring out how to adjust my model isn't worth it for my needs. I'm already going above and beyond what's needed for my project.
What I REALLY need are some better HDMI environments, ones for models to be placed on top of a table more specifically.
Thank you all for the help
You can find excellent HDRIs at HDRI haven.
However it is unlikely that you'll find one that looks like you can place something on a table.
Model the table or maybe even just the table top in Fusion 360 and then use the HDRI for illumination.
For shots like this I'd use a bit of focal blur as well to blur out the background. Then also, don't use the highest resolution HDRI. I usually use the 2k or 4k for illumination and for blurred out backgrounds.
An HDRI that would work as a table top would have to have a crazy high resolution as it needs to be good enough to not look fake. I'd model a table top and use one of Fusion 360's solid wood textures, for example.

I had a model attached that shows how to model the meniscus 😉
Nice result, nonetheless!
