I know a lot of people moving money into TIPS where you can get 2%+ real return on them. I've slowly been adding to them. I have mostly treasuries for my fixed income. When I was younger I was mostly all stocks but now in retirement I have one account to cover me until I'm 70 and that is 80%+ in fixed income so 2%+ real return is solid.

TIPs are best used in tax deferred accounts otherwise I you have to pay taxes on interest you won't see until maturity.

I would strongly suggest you signing up for a free account at bogleheads.org. A web site named after Jack Bogle the founder of Vanguard. They are mostly index investors but cover a lot of subjects especially TIPS and you can get a lot of good advice although they are mostly anti-individual stocks but that isn't your question.

You don't mention your age or what you might need this money for (retirement?).

There is also a TIPS ladder site at https://www.tipsladder.com/

Personally I've never really invested in bond funds. I prefer actual treasuries for my fixed income where I plan to keep until maturity barring an extreme emergency.

good luck
