Hedge Against Future Rate Cuts with Add-On CDs

I've been watching the rates on Fidelity brokered CDs drop as signs point to a September rate cut, so I decided it was time to use some add-on CDs as a hedging strategy against future rate cuts:

My thought is to lock in current rates with Navy Federal EasyStart Cds that can be opened with a low minimum purchase ($50) while allowing you to add additional money at any time. Current offerings are 4.75% APY for 12 months, 4.45% APY for 18 months, and 4.15% APY for 24 months, which are pretty competitive with the current Fidelity brokered CDs shown above:

My plan is to have these in my back pocket as a potential destination for future cash in the event CD rates fall back below 4% over the next couple of years. I certainly remember how attractive it was when Penfed offered 3.5% APY CDs in 2018 (Ha!), so it never fails to be prepared. With any luck I won't need them, but it's unclear how low rates could potentially get over the next year or two.
