Help choosing car seat

Hey everyone I have a 13month old currently in maxi cosi pebble pro 360. Looking for next carseat and struggling to know where to start. She is 25th centile height and weight. Looking for: - preferably isofix - ability to recline when rear facing - rear facing to minimum 3/4 years (would like extended rear facing but if can't find one to meet all criteria will just upgrade to an ERF when outgrows the seat we end up choosing) - good side padding (seen some recommended ones that don't look particularly padded round sides of the body) - to fit volvo xc60 - like the spin ability on current seat, not necessity but would be nice Price not really an issue altho would rather not have to spend 400/500 to tick all the boxes. Thanks :)
