UFB Direct is one of the banks on a website I use to pick online banks. I have 10-15 banks but not UFB Direct. I usually read some of the reviews on this site before opening an account. As long as they're FDIC insured & not really bad reviews then I don't do much other research.

Here's the short-term CDs at Fidelity.

CDs will likely have early termination penalties. If you don't want to hold for the entire term, perhaps better to consider money market type instruments. Some of the banks have accounts with MM interest rates of 4.5-5% and no penalties for withdrawal.
Some banks have/had(?) "no penalty CDs"... where you earn the stated rate, but not lower. If rates go up, you get some increase. If you withdraw before the original term, no penalty. Apparently that was too good of a deal for the depositor as it appears those types are less available now.
I had an experience with Marcus (Goldman Sachs bank)... where I had one of those "no penalty CDs". When the term was up, they asked if I wanted to roll to a new CD? I said, "sure". I presumed it would be the same as the no-penalty one I'd had before. Well, wasn't. When Marcus dragged its feet on raising rates along with the market, I moved the money to a higher yield venue. But much to my surprise, I paid an "early termination fee" of $550. My bad for presuming the new CD was the same as the old... "shoulda read the fine print", as they say.
When I did our taxes this year wifey asked, "why do we have 18 bank accounts"? Yeah, well... the answer to that was to clear all the money out of banks (except for checking for day-to-day bill paying) and moved to savings deposit money market funds at our Fidelity brokerage. Interest rate is about the same + our money is "at the ready" to deploy into equities after the great crashola and pick up bargains.
FWIW.... the interest rate on our Fidelity "core" account is ~4.3%. For amounts >$1MM, it's ~4.6%.
