Which one to buy
Pick the socket, then the brightness: 450 lm for accent lamps, 1100 lm for most rooms, 1600 lm where you'd use a 100 W-equivalent bulb. The clear E12 candle is for fixtures where the bulb shows. I haven't run these; the notes come from IKEA's US pages, the CSA listings and Matter Survey.
I haven't run any of these; the picks are based on the spec sheets and what other Home Assistant users report.
