Can anyone ELI5 how to get exposure to the 40 part of the 60/40 portfolio?

I have the basic understanding of what bonds/bills/notes are and how their prices are related to the central bank yields

Correct me if I'm wrong, the past decade a bit have been low rate environment so bond prices have been generally very high.

Now that rates are high again, bond prices are generally lowered.

But how do I actually get exposure to fixed income?

Is it smart to buy an Etf like TLT? How does the maturity date impact the investment? Am I looking for dividends or am I trading the ETFs like any other stock and sell when the yields drop again?

Would appreciate the advice!
