Car seat recommendation please

Best seat recommendations for my little girl please. She's 9 months old, 66cm and 8.26kg. Less than £350 (if possible) VW TROC (2017) currently have the Cybex Cloud T isize but doesn't leave much leg room (husband is 6ft3) planning for future when we will hopefully have another baby. So need it to fit behind him or in front seat with the Cybex in the rear seat (isofix) Hope that makes sense. TIA
