I'm currently experiencing some pretty serious vibration when I hit speeds of 50+. By serious I mean enough to shake the steering wheel, cup holders, anything in the doors, etc.

I have my tires balanced and rotated on a regular basis so I'm fairly certain it has nothing to do with the tires, though I'm not an expert. I also replaced all the struts and shocks 6 months ago for the first time in the cars life, but it hasn't improved the vibration.

My assumption for other causes would be bent axles and/or drive shaft, however I don't know anything about those, how much they cost to replace, or if replacing them would even solve the issue.

Do you have any insight or other ideas for the cause and how I can get it fixed?

If a driveshaft is bent it's pretty much due to abuse as they normally don't bend under normal circumstances unless something hit it. Have a pro check tires for balance and bulging as it may have broken inside. You can also put front tires to back to see if that changes anything. If a tire has a bulge it should be replaced immediately as they are not safe to drive on. Also have your ujoints checked.
