Vanguard's settlement fund is VMFXX, a federal money market, with a current 7 day yield of 5.27% and expense ratio of 0.11%. Sale proceeds or dividends from other holdings that are not set to reinvest, automatically get credited to VMFXX. We also use VUSXX in our taxable accounts, which currently also has a 7 day yield of 5.27% and a slightly better expense ratio of 0.09%. VUSXX typically has even less of it's dividends subject to state taxes than VMFXX, but otherwise the differences between VMFXX and VUSXX are negligible. Check-writing is a available with either, with a minimum of $250/check. It's easy to move funds between the two money markets or by ACH to a bank saving or checking account. Fidelity money markets have expense ratios several times greater than Vanguard, which lowers the Fidelity yields accordingly. For example, VUSXX would currently have about $330 per year in extra yield for every 100k invested compared to Fidelity MM.

I think the I bonds idea makes sense, and if greater liquidity is needed, just buy them more slowly rather than putting 15K in at once and tying it all up for a year. The three-month interest penalty doesn't loom large to me if you need some of the money sooner than five years: it's a way better deal than putting an emergency expense on a credit card.
