I've read several reviews of SQ PE and maybe my experience of my missing pre-departure drink was a covid thing. From what I gather, now you get a pre departure champagne (or juice of water) but in a plastic cup. You also get access to BTC (Book the Cook) but otherwise is basically an economy service with better seats.
Google "Singapore Airlines Premium Economy Review" and you'll be able to focus on the most important flights for your needs.
