Invest in Cash Plus Fund, T-Note & Bond Fund amid US Fed Rate Cut?

One of my 4D trading strategies is Diversification. Besides short term mutual funds like Moomoo Cash Plus ( $Fullerton SGD Cash Fund (SG9999005961.MF)$ and $CSOP USD Money Market Fund (SGXZ96797238.MF)$), will I consider the other investment like US Treasuries Note (T-Note) and Bond Funds?
1) Cash Plus Funds
Cash plus fund is formulated for conservative investors seeking preservation of capital and reasonable investment returns. Cash plus funds. These funds usually offer a mix of short-term debt securities and money-market investments which give the opportunity to achieve higher yields than traditional cash funds. They are designed for investors with a shorter-term investment horizon.

2) US Treasury Note
A Treasury note (T-note for short) is a marketable U.S. government debt security with a fixed interest rate and a maturity between two and 10 years. Please don't be confused with the Treasury Bill (T-bill for short) which is a short-term U.S. government debt obligation backed by the U.S. Department of the Treasury. Terms range is from 4 to 52 weeks.

3) Bond Funds
A bond fund is a mutual fund or an exchange-traded fund (ETF) that buys and sells debt instruments like government and corporate bonds. The primary goal of a bond fund is to generate monthly income for investors.

My Take:
My information about the above 3 investment products are basically from Moomoo and Investopedia. Basically my considerations of investing in new assets are as follows:
1) Stable return rate
2) Liquidity flexibility (preferably can redeem at any time with no lock in period)
3) Short term payout (preferably daily)
4) Minimum USD exchange rate risk
5) Lowest management fees
Although the US Fed rate cut may decrease the return of Cash Plus Funds, T-Note and Bond Funds, the correlation is not so straight forward as the rate cut may also impact the USD exchange rate, the stocks performance and the US economy. Basically I will prefer Cash plus fund as it meets all the 5 criterions. But l may consider investing in the other 2 products if I want to try for the long term.
