Is it any better/worse to invest in fixed-income investment right now? (Treasury notes or i-bonds, CDs, etc)

Ended up with a larger than expected tax-return and a desire to actually start preparing for any sort of long-term financial future, and I'm looking at the wider bullshit going on and assuming stocks are currently not where I want to investing money at the moment. So, what sort of fixed-income is better under current conditions, and why? And if fixed-income investments *aren't* a good idea right now, what's preferable right now and why?
