Posts below your response gave you more details..I think:
1)with a US bound flight, an early morning SIN flight might be required, so 1430 opening time is unlikely to work
2)The transfer seems like a PITA and I have not seen posts here for details. I don't even like the LHR T3/T5 transfer which is an easy one IMO, while this requires both bus and train transfer (if allowed).
The CX T4 lounge is fine for me, and if first time in SIN I would rather spend some time at Jewel instead of an airport lounge.
